Aeg washer dryer keeps blowing pump motor

[Wps]

Looking for Advice 

Aeg washer dryer keeps tripping RCD, no faults showing on machine.

Just over 2 years old

Pump had failed,

Replaced pump, and it did work on test , filled and drained

Customer did first load, and it has blown the pump once again after 40 mins

If pump disconnected,  shows pump error code, RCD not tripping when disconnected.

Is this a PCB issue?

When you say no faults showing on machine do you mean nothing is showing up on an insulation meter? Also when you say blown the pump, do you mean the pump is literally blown i.e. electrically damaged? Could water some how be getting onto the pump?

Hi

Sorry for late reply.

No faults on LED display 

Replaced pump 

Tested in spin and drain

Tested in 90 wash.

Left machine as working

 

Customer put first wash in.

All ok  filled and washed

Then at end of wash when starting to drain. Tripped RCD and now the pump motor has blown. Electrical no resistance.

 

Hope this makes sense

Hi. Have you got an insulation test meter? You can’t diagnose tripping electrics without one.

I haven't 

Can go buy one. Or are they costly 

[Whitegoodshelp]

Aye. Only engineers would normally buy them. Between £200 and £300. But without one you are working blind with fusing and tripping faults - Fusing or tripping electrics
