Question about Bathtubs & Whirlpools
Spa has been working fine until this weekend when code was found.can you give advice on how i may be able to repair myself.I am handy with most projects.
thanks for help
The condition you see on the topside control is known as "watchdog" Which usually means that the spa thinks it's "overheating"
Turn off the power to the spa for a couple of minutes, then restart, Watch the topside control if the temp. starts to climb & read a lot hotter than the actual water temp. Then it goes into watchdog, most likely you have a bad temp sensor. In some cases just resetting the spa will clear the watchdog & everything works fine. (Voltage fluctuations, "spikes" can freak out the electronics & the tub goes into watchdog to protect itself) If the spa immediately goes into watchdog when you reset it, you might have a bad board. (Let's pray it's not) 90% of the time it's a bad temp. sensor.
