    Best Robot?

    Hi All, Looks like im in the market for a new robot. Is there some sort of cheat sheet as to which ones are the best? I had a dolphin dx4, that worked ok. Something similar to that would be fine. Looking for something that has a controller of some sort so I can direct where I want it to go...

    Pollen

    Sorry is this is in the wrong thread - I honestly didn't know where else to put it. My water looks good, tests fine - except I have a lot of pollen on the surface to where it looks like dust. I have a clean filter (DE), but am unsure what to do to keep the surface of the water pollen free...

    Pentair MasterTemp 400 AFS Light on

    plug is damaged - it's a 240v that came out and I'm getting a new 240v to go back in. I'm just speculating if this is my problem or not

    Pentair MasterTemp 400 AFS Light on

    I looked at figure 20 on page 30. I believe it's 240v since this is the plug that came out of it. I didn't see any other plug in there. I'd imagine when they installed the heater years ago they threw it out since it's a 240v system On page 30 figure 22, that looks like the other side of...

    look what I found - Looks like two of the wires are completely chewed through. Could this be my problem?

    Pentair MasterTemp 400 AFS Light on

    last question (i think) for you and AJW- if you had to buy another heater - which brand would you buy? this thing is old and if the service person can't fix it, im going to break down and get a new one.

    Pentair MasterTemp 400 AFS Light on

    Is the airflow switch open or closed with the blower off? - I dont know - how do i tell? Does the airflow switch close when the blower starts? I dont know this either Does the blower run at full speed when it's on? The only time it goes on it when I jumped it and it didn't go full speed

    can it be something as simple as a bad air flow switch?

    Pentair MasterTemp 400 AFS Light on

    the diagnostic led on the module flashes once which according to the manual indicates "air flow fault" What can I do to check that? The wires although frayed look like they're making contact - i'm wondering if this "air flow fault" is the issue and not the wiring?

    it was so sunny I didnt best I could with the sunlight - This has happened once before and I think the previous repair guy used those splices let me know what you think - anything glaring about why the blower wouldn't kick on? I tried looking at the wiring diagram to figure it out but no dice

    Pentair MasterTemp 400 AFS Light on

    never mind on this. I took the panel off to check the Ignition Control Module and there was a big mouse nest and a few critters back there. They chewed the wires and made a mess. I'm going to have to call an expert to come in and fix it

    Pentair MasterTemp 400 AFS Light on

    With the wires removed from the airflow switch and the wires not connected together, measure the resistance from one terminal of the airflow switch to the other terminal. - That was the second video - the needle did not move at all. it stayed all the way over to the left

    Pentair MasterTemp 400 AFS Light on

    here is a video of when i jump the wires- it seems like it kicks on - not sure if that's the way it's supposed to be. I am a terrible electrician (i'm not one at all) so i think i checked resistance right - the needle didn't even move (video here) when i touched the two contacts together...

    Pentair MasterTemp 400 AFS Light on

    It doesn't attempt to ignite. I get a click and then nothing. All gas valves are on. Gas valve in the heater is on. I took the two blue leads off the AFS and touched them together. The AFS light on the board goes out and the blower kicked on for a bit (it's hard to keep the connectors...

    Hi All, I have a MasterTemp 400 that is getting power (board lights up) but I am getting a service heater LED on and a "click" when i hit the spa button. Nothing is firing and the blower isn't turning on. The AFS light is on on the back of the board. Here's the thing, I am not sure if...
