I recently turned on the power on my Compact A 2 group machine after it had been reconditioned only to hear a clicking coming from the right hand side of the machine. The motor did not come on to refill the boiler as it usually does for a few seconds. The right group touch-pad was dead but the left group touch-pad clicked into action but the motor did not. The coffee cup filled from the water pressure I guess. I know the electronics in this machine are a little old fashioned but as each group is acting differently I am wondering if anyone has any idea what may be wrong.

I look forward to some enlightenment (and hopefully a fix)

Champion KK!

It has blown a fuse. There are two boards nearly identical to each other and each has a fuse. This blew on one, and I had it replaced and machine want perfectly: made a coffee and then half hour later died again. There must be something tripping the fuse. Any ideas?

Same advice applies clean electronics and connections first
If that does not solve the issue, you may have a short or debris on a contact causing a short

Something out of left field - a board may have a bad track or debris causing a short

Does the fact that it goes OK for an hour or so: it fill, heats, makes a cup of coffee etc. mean anything? I would have thought a short would blow the fuse immediately. This seems to be something that is happening over the length of an hour or so and then only to one group!

Metal expands with heat so I suppose it’s possible
My gut feeling is - the culprit is a micro switch possibly connected in thermostat area controlling the on off sequence of the heating element
