heater problem

I just opened my pool for the summer and my heater isn't starting up. Hoping someone might be able to point me in the right direction. Here's what I know: Heater is a STA-RITE Max-E-Therm 333HD Control panel powers up and shows pool water temperature When I press 'Pool On', the 'Service...

Forgive me, I'm still learning here. Bought a house with an rs6, basic pool. spa overflow, pool, heater, that's it. no SWG, automatic cleaners, solar. i factory'd the rs6 b/c the previous programs were all screwed up. i created 1 program (a) to turn on the pool at 9am and off at 5pm, all...

The pool heater (I only use it with the SPA) stopped firing. It makes the noise usually heard when it is trying to start the pilot, does not stop doing this and never fires up. I checked troubleshooting (see attached file, Mini Max Plus Service Manual) and found that the lights all come on...

I have a Jandy JXI heater and 2 times now it will be heating and then when it reaches about 100-101 the blower and heater turn it self off. On the display there is no error and on the aqualink app it shows the heater is still heating. I can go to the pool breakers, turn them off for a few...

Hello, my Sta-Rite SR400NA pool water heater is making noice when it's on. Service Heater light it on. It's a 2013 heater. Should I try to service it or buy a new one? How do I find someone to service it?

We have two natural gas Jandy LXI heaters, one each to heat the pool and spa. The heaters are now 12 years old, with the pool heater dead in 2020 when we moved in and now it appears the spa heater is dead: both have check igniter issues (smell the gas, just won't ignite). Two separate providers...

Hi all, Looking for guidance from those with experience with new heater installs as part of a new pool build. The heater has never been able to complete the startup sequence and always results in a fault with 3 LED flashes for IGN SEQ FAILURE. My pool construction was completed early August and...

Hi everyone, first post here. We got our pool installed last September. Pentair setup with Easytouch 4 and Mastertemp 300. Ever since it was new we've had to walk to the pool heater and hit the spa mode or pool mode button manually when we turn on the heater from the app or the easytouch...

Our pool is only three years old, and this year it has been a thorn in our side - expensive, time-consuming and frustrating. Our contractor claims everything is out of warranty. We have had a slow leak, about 1-2 a day, which means our chemicals are always off and I'm filling with a hose every...

I have a Purex Triton Mini Max 300. When I turn it on I hear the ignitor clicking, and can watch it start the pilot light, but instead of the igniter stopping and the main burners lighting, the igniter just continues to click until eventually the unit turns off. I can see a very strong pilot...

My pool heater is about 8 years old. Has always worked as expected. However, yesterday I tried turning on the heater and it would do nothing. I have "bo" as the status on the heater front panel and when reset the heater (I turn off the breaker switch and turn it back) on I can hear the...

Dear TFP forum members, I live in southern Nevada, as the 3rd homeowner, with an in-ground pool (~16.5K gal). The pool equipment includes a Pentair MasterTemp 400, natural gas heater. I'm not sure of the age of the heater but I would say likely 6 or 7 years old. A few days ago I started the...

I'm getting beyond frustrated with my Hayward pool heater. The pool service guy was out several hours last week trying to get everything running properly. The heater is a Universal H-150 heater running on propane. The heater itself was working fine as long as I ran it in manual mode. In bypass...

I need help trouble shooting my Sta-Rite SR333HD heater. Problem: Heater runs for ~3min, gas shuts off blower stays on, system reignites, runs for 15sec, gas shuts off, repeats run/shutoff cycle 5-6 times then system shuts down and service heater LED comes on. During this time hot water is...

I have a 3 yr old Pentair MasterTemp 400 (LP) that won't light. When I start the heater, the blower comes on right away. After about 20 seconds, there's a loud buzzing noise that seems to be coming from the gas valve. It continues for 7 seconds then stops for about a minute and repeats. It...

Hello, Had a few storms recently (although not sure it is what caused the damage). I have a Mastertemp 200 pool heater and the display is blank and no LEDs illuminate. I saw that the fuse was blown. Got a replacement fuse and turned back on the breaker and the new fuse blew instantly. I'm...

I have a Pentair Matertemp heater. The problem is the heater is sensing a higher temp than the actual water temp is. I have replaced the thermister 2 times and still have the same issue. When I try to heat my hot tub I can only get the heat up to about 98 because the heater thinks it is 104...

Unit is four years old and the problem is intermittent. Sometimes it lights and sometimes not. I have removed the lid and no codes. Blower comes on you hear igniter and you smell gas and No fire. Then I take the front cover off and try again and it lights. I’m trying this morning with no luck...

Our brand new Pentair heater is broken. We're trying to figure out what could be causing it and if it's a quick fix or we'll need to make a warranty call. We are hoping it is a quick fix, since we're sharing the pool with several other families (with a google calendar so there is no overlap)...

Hi friends. Error message "high fault limit" on a 1 year old heater. Where do I buy replacement parts? How do I remove and replace? Thanks! Pics really would be helpful if you've done it.

Hi. Bought our house this past July. The heater - Mastertemp 400 - worked fine. We used it at least once per month through November. At one point - I think in August - Error 01 (Thermistor) was a problem. I replaced that, but later found the real problem was the connector on the control board...

I am getting an LP Error on my electric Hayward heater, which signifies low water pressure. I have turned the valve that normally bypasses the heater to go through the heater. For the first 30 seconds, it reads the temperature of the water and then changes to LP. What should I do next?

Good Afternoon! I have a 15x33 agp with a 20" Hayward Sand Filter and 1.5hp Powerflo Matrix Pump. Everything Works great!! I hooked up a Hayward H100ID 100k BTU Propane Pool Heater. Shortly after I start the heater I hear a popping and the inlet PVC shakes sporadically coming from my sand...

New to the Forum but not completely new to pools. Lucky enough to grow up with one in my backyard and Pops had me working on it young. Now that I have moved back into my childhood home with my fiance, I am trying to knock off the dust a bit lol. Im good with cleaning the pumps and filters but...
