This sounds like a control board failure, as you would normally see some form of life on the display panel.
The control boards can be sourced online such as the one here, the risk you face with this is there may also be other parts which have failed due to a surge\earth leakage fault.
So before buying a replacement part it is worth doing a continuity test with a multi meter checking right from the plug to where it terminates on the PCB, and then checking the pump and elements are not open circuit.
If you would like me to recommend a engineer to come and give you a quote for repair please provide your post code.
I havent heard back from you in the last few days, and just wanted to check if you still require assistance, I would appreciate it if you could rate the service received.
