Hotpoint d/w

[spark]

Hello all.Im presently having a problem with a Hotpoint Aquarius DF 23 D/Washer.
It fills heats and wash pump comes in and sometimes completes the cycle.

Problem is, it sometimes sticks in wash, i.e. wash pump operates all the time.
I know this points to a thermostat but which one is most likely to fail intermittently?

Has anyone come across another reason for this?

Many thanks

Re: Hotpoint d/w

If the water is heating then it is either cycling on the 85C stat(s) caused by localised heating (often caused by restricted lower spray arm). or the timer motor is not being turned back on by the control stat(s). You need to establish how hot the water is getting during the heat pauses.

There are two N/O stats in the door, one is 50C the other 65C. These stats supply power to the timer motor when the water reaches the correct temperature.

Other things to check:

Ensure that the water level control is not blocked. Reduced water level will cause the heater to cycle on the 85C stats.

Check that the timer motor is running and that the timer motor gear has not come off the end of the shaft.

Re: Hotpoint d/w

Thanks to both of you for the excellent replies.
This problem was indeed in the door stats.
One was o/c and the other had a burnt connection.
Replaced the two, remade connection and all is well.
Thanks again.
