Help ! We have worked out after pushing the power "on" button on the far left, a few minutes later the house earth leakage breaker trips off. ( I added a plug-in earth leakage plugin switch to the machine itself but that doesn't trip so I'm guessing the coffee machine is the straw that broke the camel's back across all house devices).
We have also recently noticed when we push the right side button to start make coffee it's started to make a slightly different buzzy noise for a couple of seconds.
I've read the buzzing is likely a failing solenoid. Can a failing solenoid trip the earth leakage ? I've looked inside and the only slight leak i can find is a high pressure pipe connection on top of the shower head between 2 solenoids. It doesn't look like much has ever leaked out. Images attached.
Any clues to the likely cause? I'm electrically minded so wanted any guidance before looking inside.
thanks for your help.
