2019 Winnebago View trauma on demand water heater issue

[Lgiann]

My Trauma on demand water heater just decided not to work, the rotary switch just blinks constantly fast and the recirculator runs, but it never lights. Don’t hear any electrode trying to start the propane and yes the LP is on, for the generator is LP driven and works . Troubleshooting guide has lots of codes, but nothing about it constantly blinking fast.. anyone have this problem before ! I am camping right now and have no hot water.. help !!!!,

You may already know this, but I’m trying to offer some help ... the Truma throws out fault codes by the long and short blinks. Mine recently wouldn’t operate because a mud dauber found its way into the flue exhaust fan. After watching the switch for several blink sequences, I was able to write down the specific shorts and longs, then went to the Truma documentation and determine where to begin.

Hi I ended up calling Truma Support and they helped me thru the issue and now it’s resolved. Issue was the unit somehow was stuck in a cleaning mode, the rotary control in side the coach was blinking rapidly, no code on the outside unit. So real hot water for 10 minutes till rotary control light went out ( and did at exactly 10 minutes ), turned unit off outside and waited 30 seconds, turned back on and voila , it’s working again... under troubleshooting guide I did not see this condition mentioned, hope this helps others who may be having similar issues, or just be aware this could happened ����
