Hotpoint WT540 washer stopping mid-wash
Hi, I am hoping someone can give me some guidance. I have a Hotpoint WT540 washer, which is now stopping mid-wash, and displaying two flashing lights on the vertical indicator (position 2 and 4 - whichever way you read it - there are horizontal lights too, but these don't come on - wouldn't a fault be indicated on these?)). I have interpreted this (possibly wrongly?) as fault 10, pressure sensor / valve. I have replaced the sensor, and as far as possible checked the hose to it (I have blown down it, and can hear water bubbling, and I have pinched the very bottom of it, and can not find a leak or split on it when blowing again).
Oh, the on on/off button flashes very rapidly when the fault kicks in
Anyone got any ideas before I hit gumtree for a replacement machine??
Thanks
Phil

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Hotpoint WT540 stops mid-wash with flashing indicator lights
- The problem
- A Hotpoint WT540 washing machine was stopping part way through a wash. The on/off button then flashed rapidly, and the user reported two flashing lights on the vertical indicator, which they interpreted as fault 10. The pressure sensor had already been replaced, and the pressure hose was informally checked for blockage or splits.
- Likely cause
- The thread suggests that if the fault code interpretation is correct, the problem could be with the EPROM chip or the PCB rather than the pressure sensor. This is presented as a possible diagnosis, not a confirmed fault.
- What fixed it
- No confirmed repair was provided. The accepted advice was that further parts should not be replaced speculatively and that the fault needs proper diagnosis before any more components are changed. Further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Observed two flashing vertical indicator lights
- Observed rapid flashing of the on/off button when the fault occurred
- Pressure sensor replaced
- Pressure hose blown through and checked as far as possible for leaks or splits
- Parts or tools mentioned
- Pressure sensor
Safety: Do not continue replacing electrical parts by guesswork. Further diagnosis should be carried out by a suitably qualified appliance engineer.

If the error code interpretation is correct it could also be a fault on the eprom chip or the pcb. Replacing parts in the hope it will fix a fault is way too risky. You have to work out for sure that a part is definitely faulty, but that can be very difficult - even for engineers sometimes. But at least an engineer will often have spare parts to try. If you have to buy each part it's a rabbit hole not worth going down.
