Stiebel Eltron 221094 - Stiebel Eltron DHC 10-2 Electric Tankless Water Heater

SOURCE: Sensor broken - E 71 - Stiebel Eltron WPF water-water heat pump.

I would check the connect first may sure it is not loose.

SOURCE: Where do I find the reset button on the Stiebel

On the Tempra 29 there is a "safety thermal cut-out" on the top of each of the heating elements within the box. I have had to open it up before to push the breaker. They are a small red plastic push button on the top. Carefully press the braker button without touching the electrical wiring inside. I hope that works for you.

The paid answerers may have a person who knows your product and the problems associated with your model.
I believe they offer a refund if the 'fix' doesn't work.
The manual might also have troubleshooting.

Each day I see 20-25 unanswered questions about tankless water heaters.
And the day before, there were same number of unanswered questions about tankless products.
The number of questions shows the complexity of the machines, the brand-specific-ness of the problems, and the inability of the manufactures to take care of their customers.
If I understand correctly, the manufacturer will refer you to the installer.
There are not many ways a do-it-yourself-er can fix a tankless.

SOURCE: heating unit in a stiebel eltron electric instant hot water heater went bad and I have to replace the unit. How difficult is that?

You will have to drain the tank, make sure when doing this to OPEN the pop off valve, the little handle on the drain pipe, or the water will not drain.
