Re: Smart mode on S1 dream

Are you on firmware version 1.24 or later? I think smart mode was added in 1.24. My Dream is not on 1.24 yet so I don't know what turning on that mode entails. I have never had problems with the LEDs on mine. I assume you probably need to replace the entire front panel. Since the controller board is...

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.

Re: "How to" replace boiler pressure valve?

If that's the problem, it is an easy fix. I would just be sure to put two wraps of teflon tape around the threads first before screwing in the new part. One last thing before doing that. You should be able to take off the warming tray with just the one screw that is at the front, center of the tray....

Re: First Repair- GFCI Trips on Startup

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?

Re: Dumb questions - attempting descale and maintenance

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...

That errant resistor circled in your photo definitely doesn't belong there. You should get it off ASAP. Is it just sitting there or is it soldered down?

Re: New to me really poorly looked after V2 s1!

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.

Re: S1 Mini Vivaldi II - strange sounds and grouphead dripping / failure?

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 ...

Re: S1 Vivaldi II boiler pump won't shut off (sometimes)

The controller board sends the signals to start the pump and to engage the solenoid based on the state of the water level sensor. So normally this indicates a problem with the water level sensor. However, it can be anything from the sensor to the microcontroller input on the controller board. Most f...

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.

I am fairly confident that swapped wires to the SSR module is your issue.
