Heating stopped

VicV

Hello,
after two years of trouble free working, system stopped produce heating. Test shows Ground Fault Error. Pressing Right side button does not change anything. The temperature is at 21 degree C with the setting at 27 degrees. I replaced the the breaker with identical one and got the same issue. Wire reds 10 Ohm resistance as per label on it.
Can the control unit cause the problem?
Thank you all who could suggest a possible failure?

And you are talking about a 3 engine triplane operating over the Bermuda triangle? or did something get lost in the model number, brand and what the heck are you talking about column?

I will try to translate:
Hello,

NOT GOODBYE

after two years of trouble free working,

My heater was working for 2 years and i did no maintenance

system

I want you to guess what kind of heater I have

stopped produce heating.

It Broke

Test shows Ground Fault Error.

I looked at the display and don't know what it means

Pressing Right side button does not change anything.

I pressed a button that I know nothing about

The temperature is at 21 degree C with the setting at 27 degrees.

And it is still broke and i don't live in the USA

I replaced the the breaker with identical one and got the same issue.

I started up the parts cannon hoping to get it right eventually

Wire reds 10 Ohm resistance as per label on it.

I have a meter

Can the control unit cause the problem?

Can you guess what might be the problem with no information at all?

Thank you all who could suggest a possible failure?

Ask me what i'm talking about and maybe i can get you some sort of info that will put you on track

Can you provide a picture or a brand and model number by chance?
We will be glad to try to help

I guess 21°C ain't that cold for @VicV

thankyou Ed
ahh, com on

21°C is 70°F. Who wants the heat set at 27°C anyway? (80°F) unless you have poor blood circulation and need it that way.


Reminds me of a story about the company that purchased my business. Prior to the sale that company which will remain nameless installed a Bosch GreenStar for an elderly customer who lives on a barrier island near Atlantic City. Shortly after the company purchased my business, I received a message that this customer may want to purchase Air Conditioning. Turns out that the customer didn't really want air conditioning but wanted to give the nameless company incentive to solve her problem. Seems she called the company 4 times with no heat. Every time the technician found nothing wrong.


I listened to her story which brought her to tears at times. The Bosch GreenStar has an outdoor reset and it was set for the most economical operation mode. That means the water temperature in the baseboard radiators was set so low that the room temperature would not rise above 71°F no matter how high the thermostat was set. You would think by the 4 service call someone would have realized that the customer needed the home to be hotter than 71°F. But no, the company policy was that after 2 nuisance service calls, the warranty no longer applied, and charged her for the 3rd and 4th service visits while the boiler was still under warranty. (the reason for the tears was that she paid $XX,YYY.00 for a new heater that did not heat, and now she had 2 more bills to pay)


I was not familiar with the Bosch GreenStar programing but since installing Buderus wall hung boilers, I knew there was a way to get the woman what she needed. I called Tech Support at Bosch and was connected to an old friend with whom I was familiar. After a brief personal conversation, he walked me thru the menu and the boiler was set to the least efficient operating mode, but would allow the boiler to produce enough temperature in the boiler to get the home to 80° if that is what the customer wanted.


Sometimes We need to Listen to the customer to really HEAR what the want and how to translate that to the technical settings of the equipment in their home that we service so they can depend on us to keep them comfortable

you went back and edited and added to your 1st response, correct?
or am I caught in too many threads?

On a more serious note, a ground fault error means just exactly that. Somewhere these is a short between one of the hot wires or even the neutral and ground. It needn't be a big blow the fuse fault -- probably isn't -- but just enough that the ground has become slightly energized.

Now. Where that is in the equipment... could be pretty much anywhere in the wiring past the ground fault sensor, which may be in the control panel. Could be in the control. Could be in an element. Could be in some of the other wiring.

They can be quite dangerous -- which is why the ground fault interrupter kills the circuit -- but they can also be fiendishly difficult to find, if they aren't obvious.

I did add some additional translations to my original comment. @VicV is asking a lot with very little input, Don't you think?

I do hope she returns with more info. I hear it's cold in Canada this time of year

a little vague, just a little,

VicV

LOL. i didn't expect to receive so many jokes on my question. I just started. Let's move on if the bait is taken. The system is Schluter® with DITRA-HEAT programmable 120V/240V thermostat.


i tried to attach some pictures of my thermostat, not realy familiar with this technology.

Surprise, pictures are here.

VicV

Here is a picture of the circuit breaker

EdTheHeaterMan

Wow that is the smallest heater I ever saw. It almost looks about the size of a thermostat.

Seriously, that is not going to help. I'm going to take a guess here and say that your are in a building that has more than one living unit, I might even say more that 5 living units. This is a question for the building management. There should be someone on site that has the specifications of that thermostat and what it is connected to. What that control is connected to is where the heat comes from, Do you have access to the mechanical room? Can you take pictures of the equipment in that room and how that control in your unit is connected to the equipment in the mechanical room?

Negative. it's a thermostat for an electrical Schluter floor heating system on the main tiled floor in a private house.

Ah. This is not good. One of the more likely places for a ground fault is in the wiring of the floor heating system -- in that main tiled floor, and this is a job for a really qualified electrician -- a really good one. It may be possible -- should be -- to isolate the flooring radiant wiring from the control and feed circuit (there is probably a junction box in an obscure location...) and determine whether the fault is in the flooring or in the wiring leading to the flooring. If the latter, it should be possible to locate it and repair it. If it's in the floor wiring...

Schluter has excellent technical service. They are a first class company. Have your installer give them a call while on site. They will get it resolved.

Btw, the Ditra heat is considered "floor warming", not necessarily "space heating".

realliveplumber

Schluter has local factory representatives that can locate, with great precision, a fault in the in floor wire, and also can locate the in floor sensors.

We just had an issue with floor sensors on a bathroom remodel job. Schluter had a bad batch go out.

They sent a factory representative from 300 miles away to assist/confirm the diagnosis, and provided the repair parts. They also paid the labor for the repairs . No BS, no aggravation. They made it right.

I have never received better customer service. From the initial phone call, everything they said that they would do, they did, when they said they would do it.

I can not say enough good things about Schluter.

Jamie Hall

Good to know,

psb75

Schluter makes first class tiling substrate materials, bond-break membranes, water proofing, wall and floor systems, shower pan materials etc. I didn't know they did electric floor warming systems. Good to know. And even better to know that they support their products so well esp. with technical troubleshooting. Thumbs up to Schluter and their products: Kerdi, Ditra etc.
