Figured it out. It was the high limit switch shutting it off. Took the header off, cleaned everything, re-seated the limit switches and now the heater stays on.

My MiniMax heater is short cycling. On for about 30 seconds then off about the same. I removed the flow switch and it seems to ne operational. Not sure how to test it. I checked the outputs and get 9.25K ohms between them whether the water is flowing or not. When unplugged the heater...

Thanks all. I'm renting the house so not about to change out 65% of the water. The CYA in the pool is around 150 and CH is around 750. We have very hard water around here and the owners of the house didn't know how to take care of the pool. They just threw in bunches of chlorine tabs and...

I have a Pentair SWG and it works great except I have to clean the calcium off it every two to three weeks. I can tell because the pressure in my filter goes up over 20 because the cell is so clogged. The hardness in the pool is off the scale, stopped adding drops around 700. Anyone else have...

OK, it's not technically in the pool but I'm wondering how to keep algae from growing on my automatic pool cover? There are folds where water stands when I extend the cover and algae grows. It's a heavy canvas or such cover.

It's a VR8304 gas valve and S8600 ignition module. I found the following in a trouble shooting guide. It's not a millivolt system. It's over 15 years old also. The pilot is only on when it's energized. How to check Gas Control Valve - Honeywell VR8304 The VR8304 gas control provides ON-OFF...

I have narrowed this down to the S8600 control module for the gas valve. I found a troubleshooting guide that told me the voltages required to operate the valve. I wasn't getting 24V on the MV terminal. I jumpered 24V to this and the heater came on. I'm getting a new control module so...

OK, it's not the pressure switch. I'm pretty sure it's either the gas control valve or the ignition module. Does anyone know what voltages should be coming out of the ignition module? I'd like to know what I should be measuring on the MV, MV/PV and PV terminals on the module.

I think I've narrowed this down to the pressure switch. Ran out of time yesterday to try bypassing it. Is there a schematic available for the controller board? It's pretty simple and would be easy to design a new one.

My MiniMax 400 pool heater is not turning the gas on. The pilot light is on. The thermostat works. It's either the gas control valve or the controller. Anyone know how to figure out which one it is? There are three wire to the gas valve, red, white and blue. I assume one of these should...

I haven't checked it out but it shouldn't be too hard. Take the cover off and make sure the boards look the same. Not sure if it uses connectors or if the wires are soldered to the board. If it's connectors then you should be able to unplug the old one and plug in the new one. If soldered...

I have basically the same situation. CYA over 100, CH 700+ (stopped at 70 drops) high TDS. I live in Ventura. Pool ~28k gal. I'd like to get an estimate on the RO. Thanks, Steve

It's leaking. The crack is about 1/4" long and it's dripping about every 1/2 sec in the motor compartment. I drained the water below the crack and the leak stopped.

I have an older Hot Springs Classic spa that has a crack in the shell. It's on an outside corner at the each of the seat. What's the best way to patch this? I'd like to do it from inside the tub and not dig through the insulation on the outside if at all possible.

Thanks, I'll try the valve at the mid position. I assumed that both we shut off in that position. I had to take the cell out to clean it. There was a fair bit of buildup. I got most of it out but cut the cleaning short when I noticed all the DE in the pool. Guess I'll have to cap off the...
