We were pulling a few shots on the Evo. During one of the shots, the pump wasn’t running as the water tank empty (AL11) sign popped up. Filled the tank, but the pump wasn’t running.

I realised the water tank / refill sensor wire connection was loose and came off. No sooner I had fixed it than the pump went into a continuous fill mode. It wasn’t stopping and something went “Pufff with steams escaping”.

I think the steam boiler’s safety value is gone as we can see from the attached video.

I am assuming the brew boiler is ok. I did complete the shot after the above incident. The coffee went straight to the sink. Shame, it was a very expensive coffee.

IMO, two things need to be fixed.

I want to remove the sensor wire and tape them properly with insulation tape. I assuming I had not wrongly swapped the white wire. For confirmation, is it as easy as removing the wires, connect them property and seal them with insulation tape.
Is it just the safety valve which needs to be replaced? Is there anything else, do I need to check?

How easy is to remove just the safety value without removing all sides? I think all the sides will have to come off for a comfortable access.

I am thinking of grabbing by the flat side of the safety value and try removing. Wrap with the PTFE tape and put it back? I believe I remove it by loosening anti-clock wise?

Assuming the brew boiler is ok.

I have a spare. Is it available locally? I would like to stock one.

If I want to just run the brew boiler, should I need to disconnect all the wires running to steam boiler, in addition to keeping it switched off at the display please ?

Thx for the help!
