Let me say first that I have 22 years of service experence, with HVAC, so I can trouble shoot if I know the sequence of operation. I was told by a so called spa mechanic that me heater was bad so I removed it and I have it in my hand. Its a Balboa5.5 kw 240v 15" 2x2 mill7.

It ohms out at 11.6 ohms.....is this BAD? The spa will run, but when the heater is supposed to kick on (i think) then the GFCI main breaker will trip.

Any help is very much apreciated.

P.S. The spa is a master spas Providence model.

The ohms reading is normal, however you probably have an element that has been invaded by water, which is what causes your gfci to trip.

The normal way to test it, is not to remove it. Simply disconnect and secure the two power connectors going to the element so they don't short out on anything. Then power it back up. If gfci doesn't trip then your element needs to be replaced.

Thanks for the fast reply page, can you elaborate on what you mean by my element being "invaded by water". I have the entire assembly next to me on my desk, and it looks as good as new, no burnt spots or hot spots. It looks like if I need a new element it is going to cost me $125 + shipping and I hate to spend that money if I dont have to this close to Xmas.
If filling the tub back up and testing as you mentioned is my only other option then so be it.

Don't go to all that trouble and expense,
just get an element for 37.00

Thanks page part is ordered should be here wensday........great site keep up the good work.

I took the advise offered on the web site and ordered the smaller KW heater.............its supposed to be easiier on the components.....I have a 5.5 but they suggest a 4.5. I s this a good idea?

Yes it is. Especially for a system with on board heater relays like the balboa system you have.

It reduces the rated current load from around 22.9 to 18.75 amps. Less stress on the contacts. Your board will appreciate you for it.

Just a follow up.......the heater arived yesterday and I put it in after work, cleaned the tub shell and filled it up last nite. This AM I sat in a 102 degree tub for the first time in many many months! Thanks again page for the guidence and help!
