I have a spa master down east model. It seems the heater stopped working. I'm seeing no circulation or flow. It shows error codes dr which means inadequate water in heater, and ohh which means overheated even though the waters cool. The water levels fine, cleaned the filter and tried running it without the filter, still no flow and won't heat.
Anything else I can try before I call a repair man?
