Whirlpool AWG997 Lost Drum Power On Wash Cycle

[mikebuk]

Hi All,
I have a Philips Whirlpool AWG997/WH washer/dryer, FA: 912300724, COD: 8537 997 15060.
It works fine apart from when agitating the wash load the drum struggles to turn. I can see the drum attempt to turn, but there isn’t enough power to make the drum move at low speed with a wet load. Spin and all other functions are fine.
I am thinking maybe a loose connection but all looks ok. The drum motor is an induction motor …… Nuova Ibmei, C.P.I. /2/16/158-AR28 and is electronically driven. The motor has 1 Yellow, 1 Green, 1 Red, 1 Black, and 2 Blue connections in addition to two brown wires from the tacho unit. The two Blue wires look to be shorted within the mortor. I’m thinking that they are maybe connected to a overheat device (thermistor etc) or are just shorted out internally.
From what I can see and have tested so far, electrical power is applied to one of the Blue connections, power passes through to the other Blue connection and then back into the Black connection via an external link on the motor plug. The Green, Yellow, Red and White I assume to be the winding connections and these go back to the timer/programmer. I get a resistance reading of between 10 and 60 Ohms from the Black to the others connections.
Having said all that, have any of you guys come across this problem before and have you any idea’s as to what might be at fault? The motor looks to be ok, so I’m looking at maybe either the timer/programmer or the motor driver. As both are a little pricey, I could do with some input from you guy first. Many thanks in advance.

Mike.

Motor capacitor no longer delivering the “kick” to start the motor. Yours is a 22uf device – if you ask spares@ukwhitegoods.co.uk for a UN1117 you’ll get sorted out promptly.

Be warned that the old capacitor can fail in a charged condition……..

Thanks for the reply. I had already ruled out the motor capacitor as if I disconnect it completely, the motor does not run at all. When reconnected, it is fine when at half speed (during a water empty cycle) and also at spin. Is it possible that the capacitor is ok for the above motor operations but not when required to just turn the drum slowly to agitate the load??? Thanks.

Replace it and see. Cheap enough.
