Serie 8 Heat pump tumble dryer WTW87560GB

[bosch2021]

Hello,

I've got a problem with our Bosch tumble dryer whereby when the power button is pressed the appliance does not turn on.

If I keep the power button pressed down the red lights around the power button (which display the program that is selected) do turn on but all of them stay on and the dryer does not work, if let go of the power button the lights turn off.

If I hold down the power button long enough (around 1 min) I get an error code E:56.

I have tried replacing the operating module (part no. 00635529) but when I install the new operating module I don't get any lights turn on, even if I hold down the power button.

Any assistance would be greatly appreciated.

Thanks
