Indesit Dishwasher DG6300 water circulation

[Johno_1]

My machine will fill and drain ok but water is not being sprayed around. I checked the motor which at some time has had water damage resulting in the windings being corroded through. I have since replaced with a new one including capacitor (at great expense) but when the cycle gets to where the motor should kick in it just emites a loud humm and does not turn. If left on the motor body heats up alarmingly. The pump is not jammed , you can turn it by hand. I am measuring 250v ac across the connecting plug when the cycle comes around however its occurred to that it may be a dc motor and theres a rectifier lurking around the machine somewhere which could be at fault. Any ideas?? 🙁

Capacitor incorrectly wired or a faulty (even a new one can fail) 🙁

The motor to pump linkage should be really very free to turn in any direction, it may also be over/under tightened?

Sounds like you may have cooked the new motor in the process though as the are not very resilient at the best of times 😯

Thanks Martin. I think the motors still ok, am still getting the same resistance across the connections. The capacitor wiring is very simple (its non electrolytic so no polarity to worry about) although I take on board what you said about even new ones can be faulty. Will be going back to the shop shortly to discuss with them.

Incidentaly what would be the symptoms if the capacitor were to go faulty (obviously if open circuit there would be silence) so i am assuming short circuit. Would the motor still run?

Can’t quite understand why the thing just sits and hums. Any clues?

The pump assembly is bolted directly onto the end of the motor and the impeler driven of an extension of the armature/rotor so theres no room for over or under tightening. The whole rotor and impeler section spins freely from either end by hand.

Many thanks again
