How To Reset A Truma Water Heater Stuck In Clean Mode?
If your heater is stuck in the clean mode, you can get out of it by resetting the heater. But there are a few extra steps involved here. So, follow these steps to the T to make sure your heater gets out of that mode and works normally:
Step 01 – Check That The Unit Is Turned On
- Make sure that the outside switch of the heater is turned on and the unit has power. You’ll see the green LED light flashing when it’s on.
- Move the control panel knob to either the “Comfort” or “Eco” position.
Step 02 – Make The Recirculation Pump Click
- Turn on all the hot water faucets to drain the water. It shouldn’t take more than 20 minutes to do it. Make sure you hear the circulation pump turn on and off at 30 second intervals during this process.
- If you don’t hear the circulation pump clicking, turn the switch off and on a few times to wake it up.
- Once the yellow light stops flashing, you can turn off the hot water faucets.
Step 03 – Reset The Rocker Switch
- Move the control panel knob to the “Off” position.
- Turn off the rocker switch, wait for half a minute, and turn it back on.
- Move the control knob dial to “Eco” or the “Comfort” mode.
Doing these things should turn on your heater and get it to work properly. If it still doesn’t work, dial the control panel knob between two different positions slowly to wake up the switch.

Unlike Truma water heaters, the Truma combi boilers do have a reset button right on the control panel. If you get a simple error code, you can just press that button to reset the code. Here’s how it looks:
However, that won’t always work. When you have a more persistent error code that won’t easily go away, you need to take matter into your own hands. You’ll have to hard reset the combi boiler.
Even for hard resetting the combi boiler, you can take different approaches. Firstly, you can take off the cover of the boiler and expose the electrical cables. Then, you can disconnect and reconnect them. That could do the trick sometimes. If that works for you, no need to look further.
But if that doesn’t work, you can press the reset button after removing the cover. Here’s what the button looks like:
When you press the button, make sure you keep holding it. Don’t release or let go. The red LED light beside the switch whill turn into an amber color. When that happens, release the reset button once.
After doing that, press it down again and hold it down for about 10 seconds and release it. The amber light will stop blinking and you’ll hear the clicking of the reset button.
If you’ve reset the boiler successfully, the amber light will disappear after the clicking sound and the green LED light will come on. Check your control panel to make sure that the error code is really gone.
