Question about Hotpoint Ultima WF860 Front Load Washer
I know this means a short circuit on the motor triac and i have had an engineer look at the machine, his conclusion was that the motor had failed but there is voltage at the motor.
What he wanted to repair the machine was at at great cost to replace the motor about the sam price for a new machine.
I am a qualified electrian and could do the repair myself but if i perchase a new motor and it does`nt work then i have spent out for a part unecessarily.
I have disconnected the plug from the motor and put the machine through a wash cycle and everything works normal except the motor of cause.
Can you tell me if i can do any tests on the motor to assure me it is the motor
If the machine is less than 5 years old and you can prove it you should get free parts on a hotpoint?
Yeah there are two/three tests you can do to check the fault, it will be better if the motor is removed, more than likley the motor will have 6 pins on the connector. two for the coil, two for the armature, and two for the speed feedback. check continuty for all three (should all be low resistance)and then check isolation from the earth, they should all be above 4 Meg Ohm from earth. then spin the motor shaft and measure a small voltage on the speed feedback (this is just a magnet that spins on a coil giving a voltage feedback during a spin)
also check the motor for cleanliness and damage to the armature( small flat copper plates that the brushes make contact with) any damage is irrepairable, the carbon dust can be hoovered or blown off which may increase the resistivity between earth if needed.
try this out and see how you get on,

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.
