Hotpoint Wm52 Should This Happen?
Hi
Basically I know my way round the inside of a washing machine but don't know if this is possible but here goes :-
Wife used the washer then put in a second load, motor did not turn but program timer was still clicking away so she switched it off. I immediately suspected the brushes, but also considered it could be the motor itself. So I replaced the brushes as they were well down, but rather than risk a blown pc board disconnected the motor plug from the board. I then started a cycle the washer went through filling with water once full switched the water valve off. The timer was still clicking away but obviously the washer was not aggitating the drum (the motor was disconnected) the washer then emptied the water ok then filled up again to rinse, it emptied again and clicked on the spin cycle but that is where the timer stopped and remained until it was manually turned to end the cycle, it does this no matter which cycle you choose ie it stops at a position of about 10 to the hour on a clock face, 10 past the hour, and 30 mins past the hour, my question is this would or should the programmer complete a cycle if the motor was disconnected from the pc board or would the programmer stop as above because the programmer was dependant on the motor being connected

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Hotpoint WM52 timer stalls with motor disconnected
- The problem
- After a first wash, the second load would fill and the programme timer would click, but the motor would not turn. The brushes were found to be worn and replaced. For testing, the motor was then disconnected from the control board, and with the motor unplugged the machine filled, drained and rinsed, but the timer consistently stopped at the spin stage and would only finish if turned manually.
- Likely cause
- The strongest supported explanation is that disconnecting the motor can prevent the WM52 timer/programmer from completing the cycle, so the observed timer stalling during the test was likely caused by the motor being out of circuit. The original no-drum-turn fault may still have been related to the worn brushes or a motor fault, but this was not confirmed. A failed element was also mentioned as another possible reason for a timer pausing, but there was no evidence it applied here.
- What fixed it
- Refit the motor into circuit and test the machine with the new brushes fitted. If the motor proves faulty, replace it with a known good unit and recheck whether the programme completes. If the motor is confirmed sound and the timer still behaves the same, the programmer would then be suspect. The exact repair was not confirmed in the discussion.
- Checks to try
- Motor brushes were inspected and found well worn
- Brushes were replaced
- Motor plug was disconnected from the board for testing
- Machine was observed to fill, drain and rinse, then stop at spin with the motor disconnected
- Parts or tools mentioned
- Motor brushes
- Motor
- Programmer
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Certain motor faults on Hotpoint and Indesit machines can cause the washer to go completely dead therefore taking it out of circuit could cause weird issues in theory.

Many thanks for that Andy, I will test out the motor and if it is faulty will replace it with a known good one then put it back in circuit to see if the programmer completes a cycle if it does then obviously taking the motor out of circuit will prevent the programmer from completing a cycle, if on the other hand the motor is ok and the programmer still acts as before then I have got a duff programmer.
I have the wm52, and I can confirm that the timer does do that if you disconnect the motor. Another thing is if the element blows, the timer stops while waiting for the temperature to rise, but of course it never does.
Just to confirm, the WM52 is not an Indesit-made machine.
Indesit took over Hotpoint in 2005. The last proper Hotpoint machines were the WMA series.
