Hi,

I have a grimac which all of a sudden when turning on trips out the power after the a while.

Further investigation found the saftey value i think is called squirting water out as the pump starts.

think that is the problem went and purchased a new one and with no luck when machine starts the pump starts and then
I get pulses of water sprays know from that same area with the new item installed. Tried installing the old part back and same issue.

Could it be the boiler.

Thanks in advance.

I think you are describing a problem with your autofill system. If you turn the machine on and it falsely thinks the boiler needs filling, it will open the solenoid and power the pump til water starts spewing out the pressure safety valve.

See:
Rocket Giotto Spurting Water Out Valve
Even though some of the advice in that thread is a little Rocket specific, I think most of it is applicable in general.

thanks for your help, cleaned parts as described in that link and looked like it was overfull with water and wasn't allowing to heat it up without spilling out.

When I drained it around 150ml it started to work normally again.

thanks
