New to the site...so I hope I am posting in the right place.
I have a Teledyne Laars Series 2 Model: ESC 400 N pool heater that is about 14 years old, and up until this season has been completely trouble free.
This past weekend my daughter and a visiting friend wanted to use the in-ground spa ( the unit has a setting for pool or spa ) never used the pool setting, but as I stated the spa setting has been used for years without a glitch.
When I turn the pool filter on, I switch the valves from pool to the spa, and then turn the switch to spa.
But now I am getting no clicking ( as in the past ) I am getting nothing. ( on either pool or spa setting )
I am hoping that someone may be able to point me in the right direction.
Thanks in advance for any assistance you can offer.
