Had a similiar problem, if the low speed pump is not turning on and there is no circulation then the water in the heater will get too hot and cause a shut down.

I picked up my new cover from Spa Depot yesterday (it was to be delivered next Monday but I didn't want to wait and the freight office is close by), I ordered it on 11-14 and it was shipped on 11-19 and at the freight office on the 24th. The cover looks great fits good and I believe is better than the oem from Coleman. I did do the upgrade to the super insulated 5"-3" and 2lb core due to our 115lb Rottweiller deciding he likes to sun himself on the cover, also got the full length thermal seal.

I just had the same OHH error on my 2003 Coleman/Maax Spa, it is a flow related issue, the low speed pump does not turn on which causes an overheat in the heater because no water is flowing which causes the system to shut down. I removed the pump and took it to an electric motor shop and had it rebuilt for $150.00, reinstalled it and it works like new.

Hello again. Thanks for your continued advice. I had a spa tech come look at this Marquis Euphoria. What he said is that the pump will not turn on. He can get it to turn on by moving it forward a bit with a screwdriver. This is the pump that does most of the work. It is located on the right side, as you are looking at the spa. It is directly underneath the Balboa control. He looked into this issue and discovered that this pump is a Vico, and Marquis no longer uses this pump. He is quoting me a rate of $120 for service call, another $80 to install a new pump, and I have not found out how much it costs to buy a new Vico pump. Does this sound consistent with your understanding of the Marquis Euphoria that uses a Vico pump? I think mine is made in 2004 or 2005. What is your estimate of cost for a new Vico pump? Is there a different pump you recommend? This spa was brand new less than two years ago. I am pretty disappointed in the pump. I use pumps for agriculture and drainage on my farm, and a good pump will last at least 10 years. Thanks for any further advice.
