Called to the above machine for the EH0 error.
The machine has done this a few times over the last few weeks. The customer has left unplugged for a while which appeared to clear the fault for a while.
Now the machine retains the EH0 error, if unplugged it clears but returns as soon as you attempt to start the machine.
As far as I can make out the error is “Voltage or frequency out of nominal values”.
The supply is OK, there are no insulation faults.
Is this likely to be a main PCB or is there something else that I need to check.the EH0 family consists of a number of error codes and you would have to go into service mode to find out which one. I agree it is most likely the board but one fault EHD mentions current leakage. Have you checked for earth faults ?
also is the model number wrong ? closest I found was T61275AC

Thanks for the info Dave,
I missed a digit out of the model. It should be MT61275AC PNC:91609746700
There were no insulation faults.
How can I get in to service mode to check which of the above is relevant?
