Hotpoint LTF8B019UK Dishwasher Leaking and Showing Error Code 05

September 04, 2026

I've been trying to figure out why my Hotpoint LTF8B019 UK Dishwasher isn't working properly. It starts and fills with water, but then it goes straight to emptying. Even when I open the door, it keeps emptying. The display shows "05" at this point, and I can't figure out what's wrong.

Hi Joan,

Thanks for your question regarding your Hotpoint LTF8B019UK Dishwasher.

It's surprising, but we found a fault in one of these machines recently. A mouse had chewed through a hose, causing the machine to leak and not fill properly. This led to an Error code 05, which means the machine can't fill to the right level anymore. As a safety measure, it keeps pumping out.

What Error Code 05 means

Error code 05 on your Hotpoint LTF8B019 indicates a water fill fault. The dishwasher's sensors have detected that water isn't reaching the correct level during the fill cycle. When this happens, the machine automatically stops and drains as a protective measure to prevent damage or overflow.

Common causes of leaks and fill problems

Damaged inlet hose — splits, cracks, or punctures allow water to escape before it reaches the tub
Loose hose connections — vibration during the cycle can loosen fittings at the inlet valve or tub
Blocked or kinked inlet hose — restricts water flow and prevents the tub from filling
Faulty inlet valve — may not open fully or may leak when closed
Worn door seal — allows water to escape from the sides during operation
Cracked tub or internal damage — less common but can cause slow leaks

What you should do next

First, check underneath and around the dishwasher for visible water pooling or damp patches. Look at the inlet hose (the one connected to your water supply) for any obvious damage, cracks, or soft spots. If the hose looks intact, check that both ends are tightened securely.

If you can't spot the problem visually, the inlet valve or internal components may need inspection. Please watch the video we've made — it will walk you through the inspection process and show you where to look for common faults.

If the hose is damaged or the connections are loose, these are straightforward repairs. We stock replacement inlet hoses and valves for the LTF8B019. If you need parts or further guidance, feel free to get in touch.
