Customer Question

Hi, I have a Maax Spa, Rio model, purchased in 2002. I have just emptied and refilled the spa after I discovered a leak at the join where the pipe leads into the heater unit. The spa had half drained before I noticed it was leaking. It appeared to be a bit loose and tightening the joiner appears to have fixed the leak. However, on start up the pump shuts down after a few seconds and the control panel beeps and displays 'H20'. The Owner's Manual does not have a trouble shooting guide so I have no idea what this means. Presumably the pump may need priming or the water sensor is not working but I have no idea how to check or fix this. The heater unit is a Spa Power 54500 Can you advise me please.

before removing something to burp air..try this.

turn unit on...turn on jets for 10 seconds and off 15 seconds...on that about 10-12 times and see if that purges the air

I had already tried this yesterday and have just tried again, and still no go. I turned unit at the power point, then pressed the auto/pump/heater button on the control unit and although I can hear the pump running it does not pump any water through the jets or filter and cuts out after about 10 seconds, still displaying H2O on control unit and after repeating about 10 times.

can you remove or loosen a fitting at/near pump and see if water present? Is pump impeller turning?

Customer: replied 1 year ago.
I am unable to check on this at the moment as it is raining here and the spa plumbing is difficult to get to. It might be a bit beyond me to loosen anything. The leaking pipe union behind heater unit was extremely hard to undo (I had assistance with this). Sounds like I may have to wait for a service person I phoned a couple of days ago to get back to me. Hard to find someone near here. I gather you are in the US, while I thought you were based in Australia (where I am).

I understand. I actually take questions from all over the world on spas, hot tubs and pools. The most popular ones are sold worldwide.

I wish you the best!
