Hello Ian. I followed your instructions, disconnecting both the motor and heater in turn. It tripped both times. With the motor disconnected it cycled through for about 2 mins then tripped. I plugged it back in the disconnected the heater ( part way into a cycle) and it tripped immediately.
Hi. Still tripped after 1 minute. Heater was completely disconnected, including earth and thermostat (?) and motor was plugged in
it looks fine, like new
It tripped after 2 minutes
Did you disconnect the mains power from the circuit board? Before you restarted?
Yes, the mains supply comes into the filter, I followed the output wire from the filter and unplugged it where it goes into the control board
OK well if it is blowing the trip with nothing connected then the problem is either with the wall socket, the plug and cable or the filter, nothing else is connected. If the appliance has got a moulded plug I would cut that off and replace with a wired one and then try it again ~ its quite common for these to fail within the moulding.
Many thanks for your help. The problem is with the supple lead / plug. Probably, I was assuming the fault would be more complex than it actually is.
