Dishwashers

Dishwashers are workhorses. A decent machine run every day will clock up thousands of operating hours over a decade of family use, and in my experience the vast majority of faults I see are entirely preventable. Blocked spray arms and clogged filters account for a huge proportion of the service calls I attend — and every single one of them could have been avoided with five minutes of basic maintenance each week. Clean the filter. It takes no time at all and it will extend the machine's life by years. That is my single most important piece of advice before we discuss any specific brand. Beyond maintenance, the faults I encounter most frequently are failed wash pumps, worn door seals, and failed heating elements. All of these are straightforward repairs — if the manufacturer is prepared to let me work on their machine. Some are. Some most definitely are not. As always, the warranty period tells you a great deal about how much confidence the manufacturer actually has in what they have built.

My Key Engineering Criteria

💧

Pump Assembly: Integrated vs. Separate Pumps

In the machines I prefer to work on, the wash pump and drain pump are separate, individually replaceable components. If the drain pump fails, you replace the drain pump. Job done. Some manufacturers — particularly at the budget end — integrate both functions into a single sealed assembly. When that unit fails, you are replacing the entire thing, which is considerably more expensive, more wasteful, and turns what should be a simple repair into a costly one. Before you buy, it is worth finding out which design your chosen model uses. Your engineer will thank you for it.

Spray Arms, Basket Runners & Filter Availability

Spray arms crack, basket runners corrode and lose their clips, and filters block. These are consumable items on every dishwasher — they will need attention during the machine's working life. The machine you buy should allow you, or your engineer, to replace them easily and at a sensible cost. If the spray arm for your dishwasher is only available as a branded proprietary part at an inflated price, that tells you something about the manufacturer's intentions. I want to see cheap, easily sourced wear parts. This is often the difference between a machine that gets repaired and one that gets skipped to landfill.

🔌

Heating Element & Control Board Accessibility

Element failures are among the most common dishwasher faults I deal with. On a well-designed machine, the element can be accessed through the base of the cabinet without major disassembly — a perfectly straightforward job that should not take long. On a poorly designed one, you can find yourself half-stripping the machine before you can even see what you are trying to replace. Control board access follows the same logic. A board I can pull, test, and swap without specialist tools is one I can repair economically. A board that is potted in silicone or buried behind multiple layers of casing is one that very often ends the machine's life prematurely.

Manufacturer Reviews

Tier 1: The Engineer's Choice

The gold standard in dishwashers — machines built to last decades, with excellent parts availability, good technical information access, and a long-term reputation that is well deserved. If budget allows, this is the straightforward choice.

Miele

Engineer's Choice

✓ Pros

  • Routinely last 20 years or more with basic maintenance — I have worked on machines from the early 2000s that are still going strong
  • Excellent parts availability — Miele take their aftermarket seriously and it shows
  • Technical information access is good for a premium brand
  • Wash performance is outstanding across the entire range
  • Pump assemblies are well-engineered and individually serviceable as separate components

✗ Cons

  • Premium price — the most expensive dishwashers on the UK market
  • Repairs still cost money — labour and genuine Miele parts are not inexpensive
  • Some of the more sophisticated feature sets add potential failure points that simpler machines do not have

💬 Paul's Verdict

The gold standard, and I say that without hesitation. I have never thrown away a Miele dishwasher because it was uneconomical to repair — they simply do not work that way. Buy one, maintain the filter properly, and it will outlast the kitchen it is fitted in. No hesitation whatsoever if the budget allows.

Tier 2: Premium Brands (With Notable Reservations)

Strong performing machines with good credentials, but each with policies or design characteristics that I cannot fully overlook. A 5-year warranty is not a nice-to-have at this level — it is a requirement.

AEG & Electrolux

Premium — Recommended with Warranty

✓ Pros

  • Very good wash performance and solid overall engineering
  • Right to Repair stance is noticeably better than many rivals — accessible technical information for independent engineers
  • Extended warranties of up to 5 years are regularly available — look for these
  • Spray arms and common wear parts are reasonably priced and available
  • Pump designs are generally serviceable as individual components

✗ Cons

  • Some proprietary sensor and control configurations add complexity to repairs
  • Build quality is a step below Miele — evident in the plastics and internal fittings
  • Not all models make element access as straightforward as I would like

💬 Paul's Verdict

A strong recommendation with a 5-year warranty, which are available if you shop around. AEG dishwashers are good machines and the company's approach to repair information is something I genuinely respect — they make my job easier. I can source the parts, I can find the technical data, and the machines are built well enough to be worth repairing.

Bosch, Neff & Siemens (BSH Group)

Premium — Long Warranty Non-Negotiable

✓ Pros

  • Consistently near the top of consumer reliability surveys — and in my workshop experience that reputation is largely deserved
  • Excellent wash performance and outstanding engineering quality on the mechanical components
  • Build quality is genuinely impressive at this price point
  • Very wide range covers all household budgets within the premium bracket

✗ Cons

  • Same no-workshop-manuals policy as their washing machines and dryers — a persistent and deliberate frustration for independent engineers
  • Branded parts are expensive and not always available outside official channels
  • Diagnostics can be restricted without dealer-level tools on newer models

💬 Paul's Verdict

I find myself in a genuinely conflicted position with BSH dishwashers. They are among the most reliable machines I encounter in the field — I cannot honestly dispute that. But the deliberate withholding of technical repair information is indefensible from a company selling premium appliances in a market that has legislated for the Right to Repair. A long warranty is non-negotiable. Do not buy one without it.

Tier 3a: Good Machine, Policy Issues

Capable dishwashers undermined by the same information-withholding policies I encounter across these brands' full appliance ranges. Mechanically manageable; electronically problematic once out of warranty.

LG

Good Mechanics, Poor Repair Policy

✓ Pros

  • Intelligent wash features and good overall cleaning performance
  • Accessible mechanical design — not the worst machines to work on
  • Parts are generally available at reasonable prices for the common mechanical faults

✗ Cons

  • No workshop manuals — the same information-withholding policy I encounter across LG's entire appliance range
  • Electronics sealed in silicone on many models — board-level repairs are impractical and usually uneconomical
  • Fault diagnosis without access to official tools can be unnecessarily difficult

💬 Paul's Verdict

Decent machines undermined by the same policy frustrations I have with LG across washing machines and dryers. I can address the mechanical faults well enough, but the moment electronics are involved on an out-of-warranty machine, the economics become very difficult for the customer.

Samsung

Good Mechanics, Poor Repair Policy

✓ Pros

  • Mid-range pricing with a reasonable feature set
  • Mechanical access is generally manageable in the workshop
  • Parts availability is reasonable for the common mechanical components

✗ Cons

  • Complex touchscreen controls on newer models have proven unreliable in my experience — and they are not inexpensive to address
  • Circuit boards are frequently potted in silicone — the same issue as across their entire appliance range
  • No workshop manuals or independent repair information

💬 Paul's Verdict

My concerns about Samsung are consistent across all their appliance categories. The silicone-sealed boards and the absence of repair information make electronics faults very difficult and expensive to deal with. The newer touchscreen-heavy models worry me particularly — more complexity introduces more potential for expensive, unrepairable failures.

4

Tier 3b: Good Policy, More Modest Build

These brands provide genuinely good Right to Repair support — accessible parts, manuals, and technical data — but build quality reflects a more modest price point. A sensible choice for budget-conscious buyers who still want a repairable machine.

Beko

Good Repair Policy, Budget Build

✓ Pros

  • Very affordable — one of the best value dishwashers on the UK market
  • Good Right to Repair support — parts, manuals, and technical information are genuinely accessible
  • Spare parts are cheap and widely available — I can always get what I need
  • Simple, practical designs that are honest about what they are

✗ Cons

  • Build quality is lower — plastic components wear more quickly than premium alternatives
  • Wash performance is adequate rather than exceptional
  • Long-term reliability record does not match the premium brands

💬 Paul's Verdict

A reasonable budget choice, particularly if you combine it with a good warranty deal. I can fix these machines and the parts are affordable — that matters enormously in the long run. The build quality is not premium, but for a busy family kitchen on a sensible budget, Beko does the job. Just maintain the filter.

5

Tier 4: Budget & Volume Brands

Functional machines at entry-level price points. Simple designs and generally available parts are positives, but build quality and long-term electronics reliability are the limiting factors. A long promotional warranty is essential.

Hotpoint, Indesit & Candy

Budget

✓ Pros

  • Accessible price point with straightforward designs
  • Common parts are generally available and not expensive
  • Simple layouts make basic repairs relatively uncomplicated

✗ Cons

  • Wash performance is adequate rather than impressive
  • Long-term electronics reliability is an issue beyond five or six years in my experience
  • Build quality reflects the price — do not expect longevity without diligent maintenance

💬 Paul's Verdict

Only with a long promotional warranty. These machines are functional and I can usually source parts for the common failure modes, but they are not built to last and the electronics have a track record I am not entirely comfortable with. Maintain the filter without fail and secure the longest warranty you can at point of purchase.

Hoover

Budget

✓ Pros

  • Functional entry-level pricing
  • Parts are generally available and reasonably sourceable
  • Simple designs that are not overly difficult to access

✗ Cons

  • Variable build quality across the range
  • Not all technical information is easy to source — I have found gaps in documentation on certain models

💬 Paul's Verdict

A functional entry-level option. I can work on them and parts are usually findable, but these are not machines I would buy expecting a long service life. The standard advice applies: get the warranty and clean the filter regularly.

Tier 5: Newcomers to the UK Market

Brands I am watching with interest but cannot yet recommend with engineering confidence. I have not seen enough of these through the workshop to tell you how they age — and the UK service infrastructure for independent repair is not yet established.

Haier

Newcomer

✓ Pros

  • Growing UK presence with competitive pricing
  • Feature set is improving year on year

✗ Cons

  • Long-term UK reliability data simply does not exist yet — I have not seen enough of these through the workshop
  • Service infrastructure in the UK is limited for independent repair
  • Technical information and parts sourcing can be difficult

💬 Paul's Verdict

Haier are pushing into the UK dishwasher market and I am watching with genuine interest. I cannot give you a confident engineering recommendation yet — I need more workshop hours with these machines before I can tell you how they age. Keep an eye on this space.

Hisense

Newcomer

✓ Pros

  • Competitive entry-level pricing
  • Retail presence is growing across UK outlets

✗ Cons

  • Very limited UK service and parts network for independent repair
  • Long-term reliability in the UK market is unproven
  • Technical information availability is not clear

💬 Paul's Verdict

Same caveat as Haier. The price is tempting but the support infrastructure for independent repair in the UK is not there yet. I would want to see several more years of UK market data, and a few of these through my workshop, before I start recommending them with any real confidence.
