Beko washing machine overfills on second fill on most programmes

The problem

The Beko washing machine was reported to overfill on the second fill on all programmes tried, although the original poster later said it did not overfill on the woollens wash. The pressure switch and pressure tube had already been replaced, and the pressure chamber was checked by blowing through the brown pipe, with bubbling heard, suggesting it was not blocked.

Likely cause

The accepted reply said the strongest indication was a fault in the pressure system rather than a sticking water valve, particularly if switching the machine off stops the incoming water. A small air leak in the pressure system was suggested as a possible explanation for overfilling that appears after the first fill.

What fixed it

The recommended action was to observe whether turning the machine off during overfilling stops the water intake, to help distinguish a pressure-system fault from a sticking inlet valve. It was also suggested to test the filling behaviour with no laundry inside, because soaked laundry can cause normal topping-up and confuse the diagnosis. No exact repair was confirmed in the discussion.

Checks to try

• Pressure switch replaced
• Pressure tube replaced
• Pressure chamber checked by blowing through the brown pipe
• Listen for bubbling in the pressure chamber/pipe
• Check whether turning the machine off stops the water running in
• Test without washing inside
• Compare behaviour on woollens wash versus other programmes
