You should get service manual and new ohm meter to check parts.
If tools are no good, results will not be good in any case.
I do not compromise on tools quality.
D board replacement is so early decision. As I told you, +22 and -22 should be available in D board. If such voltages are not there, how can convergence ICs carry out the job?
Please have service manual on any online manual store and check power supply area, why +22 and -22 are not being supplied.
Pico fuses should be checked out of board or at least one pin should be unsold to test fuse.
In circuit test of fuse is not good idea and can misguide you with wrong results.

I know this may sound stupid, but check that you have the earth wire from the mains connector, athinish black wire connected to the terminal on the mixer. My Kenwood would not run after i made a capacitor repar. The motor just "Buzzed" until i put the thin black earth strap back onto the casing.
I sincerely hope this helps,

The main control needs to be replaced along with the RPS. Whirlpool had a recall or is aware of this problem.

Check the low oil sending unit.(Make SURE there is enough oil in the unit) Take the 2 wires off and join together. If the unit starts, then replace the sending unit and put the 2 wires back on. good luck

Zanussi washing machines can sometimes display error code E50. As John Lewis washing machines are currently also made by Zanussi some John Lewis washing machines can also display error E50.
Unfortunately this is not a "proper" error code and is not listed in error code lists. It's part of the motor fault error code group and is apparently displayed to customers but when an engineer enters a special diagnostic display the "proper" error code will be displayed giving more information.
However, there are usually only two error codes beginning with E5 which are E51 and E52, which are "motor power triac short circuited" and "no signal from the motor tachometric generator" respectively.
So if you have E50 displayed on a Zanussi or John Lewis washing machine it looks like a problem with the motor. However, the E51 "motor power triac short circuited" could be a fault on one of the PC boards as triacs are usually on printed circuit boards. This could have blown due to a short circuit somewhere else (like the motor for example) - I would advise that an engineer is required if you can't see anything obvious with the motor.
