Re: 2 year old Lucca- troubleshooting questions

A couple of things:

1) You specified that the problem was the over pressure valve, but what you described is the Vaccum Breaker Valve.
2) Water will not come out of the VBV ever if the water level sensor is working properly.

Normally the gauges fail by not returning to zero which causes a linear offset.

If this results in a good pressure and you can live with it, there...

They make 1-hole, 2-hole, and 3-hole tips plus a 4-hole tip with bigger holes. Some of these would probably make it easier for you, like training wheels. However, the currently shipping tip (assuming no recent changes) is the most loved of all by users. While you are getting a handle on it, the easi...

Re: No flow from group head and hot water tap

I bought mine from Chris Coffee many years ago. It was nowhere near as nice as the one below that they currently carry and was probably 1/2 the price. I originally bought it with the 1/4" JG fittings, but later upgraded it to 3/8". For the S1 V@ or Dream preinfusion where the water just runs in at l...

Re: No flow from group head and hot water tap

The hot water flow is completely determined by a solenoid valve. Either the valve is mineraled over inside so that it is stuck closed or else the solenoid itself has failed. If you press the hot water button do you hear a sharp click? If so, odds are the solenoid itself is OK and you probably need t...

Is it also safe to assume by the age of your machine that it is a plumbed-in, rotary pump machine and not the vibe pump, tank "Mini" version?

Re: Impending failure?

There's one of those one way valves built-in right behind the tank to keep water from running back out and into the tank. If this valve is leaking water back into the tank perhaps the pump could partially lose its prime the next time it is run. To test this I guess you could pull the tank out for a ...

It sounds like you bought the machine with the mechanical pre-infusion already installed. If not, you would have the bolt that goes in the hole where the preinfuser attaches and you could do a quick test by removing it to confirm that it is not causing the problem.

Unplug the power cables from the boiler heater elements,then turn it on and see if it still trips.

Remove the right cover. You will see the white plastic pieces sticking through holes in the side of the chassis. Just pinch the ends with a pair of pliers, preferrably needle nose, and push through the hole.

Taking them both out will also give you a chance to dust under them, too!
