I have a code 188 on my jacuzzi hot tub - Jacuzzi Bellavista 6 Whirlpool w/2-Speed Motor JAC-EE20

Maybe these folks can help they stock allot of Jacuzzi parts.

Hi,

Please attempt to start the jacuzzi without any water and see if it functions. Then you can fill the jacuzzi up to 1/4th with water and check if it continues to run. If so, continue to one half full. If this jacuzzi breaks down at these water levels, then you'd need to call the manufacturer to advise on what part needs to be changed to get everything working again. Thank you.

Sounds like a problem with the thermostat.

This issue will have nothing to do with the jacuzzi tub. You will find the problem exists in the way your home was plumbed by the plumber.
Somewhere there is a clog in the water line going to the hot water faucet.
Find that and you will solve your problem.

Jacuzzi has the manuals online if this is a jacuzzi brand hot tub.

What kind of controls do you have? Electronic it sounds like but do you have a model number of the control box under the tub?

Kathy,

I think what you're looking at are the part numbers for the heater and control systems used in some Jacuzzi hot tubs rather than the Jacuzzi model number. I ran into the same issue and discovered through some cross-referencing on the web (jacuzzi parts suppliers) that this is the part number control unit made by Balboa. Odds are they were used in multiple Jacuzzi models.

My suggestion: Look here http://clearcreekspas.com/model_id.html to identify the control panel for your Jacuzzi and then follow the link to the correct manual. Some cover multiple models so you will need to know the electrical requirements of yours (120 V or 240 V?) and then check the layout of each tub shell to determine which model is yours.

I figured out mine is a Jacuzzi Essence Model 350 this way.

Good luck!
