Truma error code

We took our new to us 2016 Sunstar to a local rv park for our first ever rv experience.

Prior owner installed a Truma tankless water heater. Worked fine at home over the past month.

Pulled into rv park, turned it on and no hot water.

Itís flashing a code 6 which means one of 4 sensors are open wos, eos, eps, and bos. Code sequence was ssssslls. I reseated all connectors I could reach and rebooted about a dozen times.

Any common fail point on these?

Have you tried calling the company that makes the water heater?
