Re: Is this normal?

What temperature is the group set to? If the temperature is OK, you may need to reset the group pressure. Since you don't have a built-in group pressure gauge you should either buy or make one. The portafilter is the highest cost item. My machine came with two so you could use one with a single spou...

Re: Low pressure at group head

Unless new or European models have added a switch that older, US models don't have, there is no volumetric doser switch. The only switch I am aware of in newer models is the one on top of the plastic box holding the controller board. This is set to off when you do NOT have the optional timer switch ...

Re: Low pressure at group head

Did you accidentally knock one of the wires off the volumetric doser while replacing the pump? A doser error is what you are getting. If the wires still seem to be correctly attached, unscrew the doser lid, remove the plastic rotating water vane, and check inside the body for debris that might be bl...

Re: Water temperature

Does the front panel temperature display indicate that the group boiler is up to temperature? If yes, then the most likely failure is the temperature probe itself. As I recall, the V2 Mini uses a different style temperature probe on each boiler so you won't be able to easily swap them to see if that...

Re: First Repair- GFCI Trips on Startup

17 Ohms is correct for that heater element since R = V2 / P = 1172/ 800 = 17 Ohms.

Also, since it only takes 5uA of leakage current to trip a GFCI you won't see any change in resistance when using an ohmmeter with the cord unplugged.

What Clive is calling a Safety Switch, LaSpaziale calls a Safety Thermostat. It's actually a heat thermostat. If the boiler gets too hot it trips and removes the voltage from the boiler heater element. There is one on each boiler. So, "No", the boiler won't work when you disconnect this wi...

Re: Odd part on S1 VII board, and autofill problem

Water or condensation does tend to get inside the heater element over time. Usually it just trips the GFCI breaker on the circuit. This is a first I've heard that it interfered with the fill sensor, though I can see how it would. Do you have a GFCI on that circuit?

The large O ring for the boiler lid should be obvious from its size. I assume the rest of the O Rings are much smaller. Most of these probably go in the steam arm, the steam arm valve assembly, and the hot water arm. I wouldn't take anything apart to check them out unless one is already leaking. The...

The triac on the steam boiler triac board is shorted. You can either replace the triac or buy a new board. It fits all your symptoms. That may have been what took out your steam boiler element to begin with.

Interesting. I've either never noticed the 2A fuse on my Dream or else they added it after mine was manufactured. Given the purpose of the 2A fuse, it sounds like the motor has either gone bad or else the pump has mechanical issues that are loading down the motor.

While you have the cable disconnected from the 3-way valve solenoid, check the power across the leads. Since you are in Germany that will be 230V AC. There should never be voltage on those leads when you just plug the unit in. Even when you turn on the machine there shouldn't be voltage there until ...

A 1.8 bar replacement sounds fine. If the original valve really pops off at 1.5bar, that's pretty marginal since the normal boiler pressure is about 1.3bar.
