I upgraded my Truma AquaGo Basic to the Comfort mainly so I can decalcify the system myself. I followed the directions in the manual to the letter and all went well, or so I thought.
In preparation for an upcoming trip I tried the water heater and surprise, it would not ignite, no matter what I did. I did this on Saturday so this gave me something to worry about all weekend
I called Truma this morning and before I finished my first sentence, Chantal asks for my email and sends me the “better Instructions”. By the way, Truma support was awesome. After following the instructions below, and flushing the system for 15 minutes the heater returned to normal.
I have included her email below to make it easier for anybody needing to decalcify.
Coming Out of Clean Mode
Power to the unit must be on from the main panel
The outside switch needs to be in the “ON” position
Turn rotary dial on inside switch to “ECO” or “Comfort” mode (these are the top 2 positions on the switch)
Wait until you hear the circulation pump cycle on and off
Open all the hot water faucets in the vehicle- let the water run until the yellow light stops flashing, this could take 15 minutes or so. (During this time you will hear the circulation pump turning off and on in approx. 30 second intervals this is normal. The burner will not ignite)
Once the inside switch stops flashing turn off water
Turn rotary dial to the “off” position
Turn the rocker switch on the AquaGo to the “off” position wait 30 seconds
Turn rocker switch on the AquaGo back on
Turn the rotary dial to the “ECO” or “Comfort” mode (you may need to wake up the dial by turning it on and off a couple times)
The unit should work normally at this time.
Kindest regards,
