Miele w524 Prestige plus tripping rcd

[pandrews]

Hi

When the washing machine is on and filling up with water, a little while later, the rcd trips.

If its on a drain / spin program, it works without any issues.

There’s no obvious leaks from what I can see with the top cover removed.

I did also try to select the cold program, and a little while later, it also trips the rcd.

This leads me to think perhaps the heating elements need replacing. But before i do this, can someone advise me where this part is?

Which cover of the washing machine should I remove to access? I have multimeter, and if someone can also advise what the reading should be if it’s defective?

Thanks

Ok found the heating element which was accessible by removing the front cover.

Took reading

Heating element: 23.6
Heating sensor: 16.17 k

Any advice regarding the above readings?

its the reading to earth that matters

should be millions of ohms

Hi Dave, thanks for the info.

Have checked the heating elements to earth: 2.1M ohms

What does this reading indicate? If it’s defective, would this cause the rcd to trip?

Thx

2.1 is not bad

the 2 most likely parts to cause this are motor or heater

as a quick test, disconnect the main heater wires and try the machine to see if it trips

Interesting, I did what you advised – it’s not tripping.

Previously, as soon the water is filled I.e. prior to the heat up, it would trip.

Time to replace the heater? Where can I find the part number from?

Thanks

double check but this looks correct
