Got a Hayward H400FDN heater. The front display suddenly started displaying "Service" and "Standby" mode. Replaced the front bezel after Google search. But after installing the new bezel/display, it is completely blank (with either new old old bezel). Checked the back of the board and it...

Got a Hayward 2-Speed North Star pump; need to replace that. I don't think they make North Star anymore. Any thoughts which pump should I go with? TraiStar/Super II or something else? It's a pool and spa. Thanks in advance.

I got an AquaLink RS controller (probably ~ 8 years old!). The AUX 3 and AUX buttons were working well for the pool light and spa light. But they suddenly stopped working. Got a PDA type remote controller. Can't turn on the lights neither from the PDA nor via the control box by the pump. I...

Hope somebody can help. After cleaning my pool yesterday I started the pump and I inadvertently pressed the "AUX 1" switch at the same time ("AUX 1" switch is for the the spa aerator that we never use). The pump stopped working (it did humming for few seconds and then nothing happened) . I...

I have an old AO Smith 7-184874-01 motor on a 2 Speed Hayward pump. The motor burned and I got a new 2 Horse Power Century B2979 pump (learned that the current motor is end of life). Need help on the wiring. The old pump has one green (assuming this is the ground) and three other wires...

My timer is no longer working. I got two 101M Intermatic timers (one 120v and the other 240v) -- but found that none of them is the right match. I am guessing this is 103M (which is no longer in production, but available on eBay/Amazon etc.) -- but looking into the photos of 103M, the wiring...

Pool is losing water via main drain. Every time I run the pool (normal operation) water is flowing out through the main drain and I need to add water to the pool. If I put the valve on recycle mode, there is no water draining via the main drain. However every other setting lets the water...

I was working on the pool; everything ok. Heard a click noise from the pump area and then the filter pressure dropped from 15 to 5 PSI. Water is still flowing through the pump/filter, but lots of bubbles in the pump basket, very slow water flow from the return. Replaced the pump basket...

I started servicing a new salt system pool. It has two fountains; one of them looks perfect, but the other one has black algae. I tried to brush that with little luck. Can anybody please recommend any chemicals and/or anything else on how I can remove this algae? Thanks and appreciate your...

Hope somebody can help! I am working on a Hayward H250FDN Heater -- apparently the front panel leaks water inside the heater. I opened the panel and lost the little buttons under the up and down keys! Can you please advise?: 1. Where can I get the little buttons from? 2. Is there a cover...

Hello Everybody, I am working on a pool; the pump is not working -- when I start this it does some noise and then nothing happens. So I stooped the pool. I am assuming the motor/pump needs replacement. Can anybody please advise on:? 1. Should I replace only the motor or the whole thing (the...

I just installed a brand new Polaris 360. However it is not working properly. Couple of things: 1. The backup valve continuously sprays water 2. The Polaris runs really slow (didn't check the RPM, but this is definitely less than 28) 3. It does not pick up leaves 3. After running for a while...

Hello Everybody, I am very new to this forum and really liking this! Currently working on clearing up a green pool, hope you can help: 1. Pool was a swamp (not even green, it was brown when I started!) 2. Vinyl pool, 18,000 gallons, above ground, sand filter, brand new pump 3. Added lots of...
