Hotpoint LTF 8B019 UK Integrated Dishwasher Shows E5 Error

Hi Meggie, sorry to hear about the problem with your Hotpoint LTF 8B019 UK Dishwasher,

Because this is an Indesit/Ariston chassis, a flashing '5' (or A-5) on this specific model is heavily tied to the water draining, circulation, and pressure switch circuits. The machine essentially loses track of its internal water level during the cycle.

Here is what to tackle on the bench:

• Filters, Mesh Plate & Microfilter: The error is frequently linked to a blockage in the mesh plate, filter, or microfilter. When these are blinded with food debris, the circulation pump gets starved of water, preventing the pressure switch from physically engaging.
• Pressure Switch: The water level pressure switch itself is a common source of this fault. It is always worth checking the air chamber and the tube leading to it for hidden grease blockages before replacing the switch.
• Drainage & Waste: This error is primarily associated with a water draining issue. Be sure to check the waste plumbing connections at the sink unit to ensure the machine isn't struggling to clear old water.
• Circulation Pump: The circulation pump is another potential failure point that can trigger an A-5 fault on these models. If the motor is jammed with glass or failing, it won't generate the necessary water pressure.
• Air Brake Turbine: If the main circulation and drainage components are in working order, the air brake turbine (flow meter) is known to occasionally fail on this specific model.

I've also linked some videos at the bottom of the page to help fix your problem. If you have any further questions, please don't hesitate to ask. I would be glad to help you fix your problem. Have a good day, Paul!
