    Hot Tub / Spa Covers - what features & thickness needed vs overkill?

    Most covers look the same, or nearly the same... its difficult if not impossible to know which are better quality built and what features are actually useful. Prices are crazy considering whatever I buy is worth more than my 13 yr old hot tub itself. And to get a replacement spa of the same...

    Replacing Balboa VS500Z board with different revision - 1 difference cant figure out.

    I was told even though boards have the same model numbers and revisions they dont all act the same... Balboa sux. The board I got doesnt seem to work with my VL01S pad, no matter what chip its running. What a load!

    Replacing Balboa VS500Z board with different revision - 1 difference cant figure out.

    I'm buying a new topside. I found a Balboa doc that said do not lug in topside with LED backlights into J2. I wonder if I accidentally did this and blew the circuit? Its just odd that it was working prior to the board swap.

    Replacing Balboa VS500Z board with different revision - 1 difference cant figure out.

    I think the VL701S is dead... I tried several other ethernet network cables to see if that was it... the topside is not powering up at all.

    Replacing Balboa VS500Z board with different revision - 1 difference cant figure out.

    Yes, A3 was ON with my original board. I have tried it both ways. I'll try again this afternoon resetting the Memory. Odd that the Balboa 52144 VL200 Mini Oval is lighting up but the VL701S is not. I tried both plugs on the board too.

    Replacing Balboa VS500Z board with different revision - 1 difference cant figure out.

    I did try to reset the Persistent Memory. No difference... the existing VL701S Topside doesnt seem to power up at all where the VL240 does. The VL701S was working fine with the old board All pumps are 240v -- they run fine when using the Balboa 52144 VL200 Mini Oval topside (one that came with...

    Replacing Balboa VS500Z board with different revision - 1 difference cant figure out.

    Well guys, I tried to place the white wire that went to W4 to the Red AC bank, that seemed to be logical. BUT, when I turn on the system, I hear a click and nothing displays on the Topside control panel. The breaker doesnt trip, and no smells. The prior system (one I replaced my pack with)...

    Tips To Reduce Pump Sound And Vibration?

    I think FatMat is an asphalt based mat... that would definitely add mass. I might just go buy some asphalt base sheet at Home Depot and try that. What would you use the urethane spray foam for - coating the doors of the cabinet?

    Tips To Reduce Pump Sound And Vibration?

    I bought a home with a older hot tub, has two pumps (1 speed, and 2 speed) I had to turn the spa so the pump side now faces the home and the noise level has increased 2 to 3x. After some troubleshooting, I found much of the noise entering the house is from vibration of the enclosure when...

    Breaker trips after 2 minutes - heating element?

    What is the normal OHM reading on Balboa M7 5.5KW? The OHM reading is 12-13... so it is not broken. Could it just need a cleaning? The spa is a Keys Backyard 211D... uses a Balboa VS510Sz
