Hotpoint pump replacement
HI,
I have a Hotpoint WMD962P washing machine with an F11 fault. This appears to be a drain pump failure, after watching a tutorial on espares I removed the old pump, an Askoll M231 and checked the resistance which was at 266, apparently should only be 230. So i ordered a replacement. The new part is an Askoll M231XP with slightly different pin configuration but, more importantly, is rated at .2A and 40w, where the old is .2a and 34w. It is proving very difficult to get the exact part as the machine is over 10 years old. Is it worth fitting the 40w motor or should I hold out until I can get the 34W?

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Hotpoint WMD962P F11 fault not confirmed as drain pump failure
- The problem
- Hotpoint WMD962P washing machine showed F11. The owner initially suspected the drain pump and removed the fitted Askoll M231 pump. Resistance measured 266 ohms, and a replacement Askoll M231XP was obtained, but it also measured 266 ohms. The owner was unsure whether to fit the 40W replacement instead of the original 34W pump.
- Likely cause
- The discussion did not confirm a failed pump. The strongest supported diagnosis is that the fault may lie elsewhere, depending on whether the machine actually drains. If it pumps water out, a pressure system blockage was suggested as a possible cause. If it does not pump out, the fault could still be in the drain system or related control side, but this was not confirmed.
- What fixed it
- The accepted advice was that the small resistance difference was unlikely to prove pump failure, as pumps are usually open circuit when faulty or show a resistance and run. Recommended next step was to diagnose by symptom: confirm whether the machine is actually pumping water out and whether it is left full of water. If it drains, investigate the pressure system for blockage. Exact repair was not confirmed.
- Checks to try
- Old Askoll M231 pump resistance measured at 266 ohms
- Replacement Askoll M231XP pump resistance measured at 266 ohms
- Drainage channels checked and reported not blocked
- Advised to check whether water is actually pumped out or the machine is left full of water
- Parts or tools mentioned
- Askoll M231 pump
- Askoll M231XP pump
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

I wouldn't have thought such a small difference in readings would make any difference. With a pump, they are usually either open circuit, and don't run, or there's a resistance reading and they run.

Thanks for the reply, since my post I have come to the conclusion that the pump might not be the problem. The new pump measured the same resistance, 266 ohms. Base on that fact I think the issue lies elsewhere, maybe the control mechanism that tells the machine to drain is screwed up. I checked all drainage channels are not blocked, so must ne motor or controller, as an ill educated guess.

That's what I thought, thanks for the update. This is the problem with error codes, they just take over and hide the actual symptoms. What you need to ask yourself is, is the water being pumped out or not? Is the washer left full of water or with the water pumped away. If it's the latter then it doesn't matter what the error code says it can't be a pump fault. A pump fault just stops water being drained away. If water is being pumped out but the washing machine thinks it isn't, then that can cause the error, that can be caused by blockages in the pressure system.
