    Intellichlor IC40 red and green flashing lights

    Replaced 4 wired switch with 4 wire switch, with color translation as in the image below, the 4-to-4 (except that for one wire the switch has a see through insulation for what should be white). Flow switch has arrows (externally) so flow can be aligned: I assumed the arrows point in the...

    Intellichlor IC40 red and green flashing lights

    My intellichlor IC40 has red and green alternating flashing salt level lights low-good; a steady red light for flow. Just like in this video pulled from the web: There are many posts about this and I have had this condition before. Yes, I have had the pool chemicals tested and they are all ok...

    Mini max Plus 400 not firing, service light on, all other troubleshooting lights on

    Thanks! It seems to be working fine. I was sure to move the valve all the way to ON (a little past it actually, until it clocked). Glad I did not agree to have the heater replaced (not yet!)

    Mini max Plus 400 not firing, service light on, all other troubleshooting lights on

    Hi swamprat69 -- if you are still there Let me start with the questions and below I will describe how I go to this point. After opening the panel I noticed that he Gas Valve (item 17, part 073998 in the diagram for minimax plus) was switched off. Switched to on and bingo, everything works! Here...

    Mini max Plus 400 not firing, service light on, all other troubleshooting lights on

    It's more like a glow than a spark, and a very faint glow at that. I am looking at it from below after removing the front panel of the heater, but of course is not very direct -- still I do not think my view is blocked. So a faint spark could mean there is some dirt or rust on the electrode? If...

    Mini max Plus 400 not firing, service light on, all other troubleshooting lights on

    I do see a spark at the pilot assembly, but no flame. To be sure I waited until dark and I see a faint glow at the assembly that turns off correlated with the RAT-TATA sounds (which I am free to turn on/off by turning the spa heat pot)

    Mini max Plus 400 not firing, service light on, all other troubleshooting lights on

    Thanks for the response and sorry to take time following up (went to work). The pilot is not lighting. I removed the heater cover and looked right into it, where you described; the ra-ta-tah continuous noise comes from there, but no flame

    Mini max Plus 400 not firing, service light on, all other troubleshooting lights on

    25 years old. Was working fine up to a month ago or so. I don't use often. Then a couple of times a few weeks ago it started heating from 60F got to about 75 and stopped. Pool guy came and replaced the high limit sensor. After that it worked once, got to 100 and then it stopped, would not start...

    Mini max Plus 400 not firing, service light on, all other troubleshooting lights on

    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...

    Pentair Intelliflo in EasyTouch 8 system no longer gets power

    Hi Jim Thanks again! So there are three leads, two read and one green. I assumed the green is ground and measured 240V between the two reds. Juts for completeness, between either of the red and the green is 120V. (BTW, teh cover of the pumps' control panel was off for the picture -- I do have...

    Pentair Intelliflo in EasyTouch 8 system no longer gets power

    Thanks, Jim, I do have a voltmeter, so I can go ahead with the measurements, but let me understand. First "the pump has no lights and no display" do you mean that the LED's on the control panel on the pump do not light up? (The picture I attach sown the panel) If that is the case, answer is LEDs...

    Pentair Intelliflo in EasyTouch 8 system no longer gets power

    I have a Pentair easytouch 8 with an IC40 and a VS intelliflo, installed 10 years ago. Was working perfectly until tow days ago. After city blackout two nights ago and power restored, the pump (intelliflo) won't go. Easytouch has power as does IC40, but pump does not seem to have power, not...

    scale buildup in cells of intellichlor IC40, needs frequent acid wash

    How can I tell if the plates are damaged in such a way as to prevent cell reversing? Also, if they are damaged, can I replaced the damaged plates only (as opposed to replacing the whole chlorinator, which is a hefty expense)?

    scale buildup in cells of intellichlor IC40, needs frequent acid wash

    Here we go, from my local pool store: FAC: 5 TAC: 5 pH: 7.5 TA: 100 AA: 100 CYA: 20 Calcium Hardness: 400 salt: 3400 phosphates: 100 The chlorine seems high but that's intentional: I ran it at high all day yesterday since it had dropped low since I had postponed cleaning the salt-cell a bit. I...

    scale buildup in cells of intellichlor IC40, needs frequent acid wash

    After 4 years of working with little need for cleaning, my intellichlor IC40 now requires frequent (about every 1-to-2 weeks) acid wash else it will not produce chlorine. The reason is pretty obvious, it builds up significant amount of minerals between the plates, near the top and bottom edges...

    Pacfab Minimax Plus 400 heater is short cycling

    I never followed up on the replacement of the Flow Valve assembly: it was straightforward to replace and the cycling problem immediately disappeared. Works like a charm

    Pacfab Minimax Plus 400 heater is short cycling

    I have some success to report, I hope this is useful to others. After I finally got a hold of the actual SERVICE manual (as opposed to the Operations and Installation Manual) many things became transparent. There are clear step by step troubleshooting instructions. It took me 10 sec to...

    Purex Triton Minimax Plus Service Manual

    On p.23 the Operation and Installation/owner manual says "Please consult the latest edition of the “MiniMax Plus Service Manual” for complete service and repair instructions." Anybody has a link to the Service Manual (which is NOT the Operation and Installation Manual)?

    Pacfab Minimax Plus 400 heater is short cycling

    As you can tell from my reply to Qwaxalot, the answer is no. I do have to add that the progression to where I am now is precisely how you describe it for yours (including the behavior of warning lights and of moving the dials slightly form max and the heat turning off, among others).

    Pacfab Minimax Plus 400 heater is short cycling

    Dear Qwaxalot: Here is what I got from Pentair's support, after one week wait to hear form them: "The problem could be upstream somewhere in the safety loop. Was the heater showing a water temperature? Did the fan motor turn on and blow cold air out the side?" To which I replied: "I am...

    Pacfab Minimax Plus 400 heater is short cycling

    Let me add to previous: 1. I noticed the power light is always on, regardless of state of Easytouch. 2. I opened the panel and bridged the rocker switch: the power light stayed on and the heater did not start.

    Pacfab Minimax Plus 400 heater is short cycling

    Power light does come on. I tried to rock the rocker switch in both directions, no difference. I can disconnect, dismount and test, but perhaps you have a better idea?

    Pacfab Minimax Plus 400 heater is short cycling

    Yes,I have a copy of the manual. Light indicators: this is weird, I went out to look at them after I read your post and now I got (for the first time) the heater won;t come up at all. As I tried this by turning on the SPA from my remote(Easytouch) while the pump was in the cleaning cycle, I am...

    Pacfab Minimax Plus 400 heater is short cycling

    My Pacfab Minimax Plus 400 heater is short cycling (turning on and off rapidly). The troubleshooting section in the manual suggests the problem/remedy may be one of the following: 1. insufficient water flow/clean filter 2. defective wiring/repair or replace wiring 3. defective flow valve or out...

    Update on Field Calibration for the Intellichlor IC40

    I removed the cell and visually inspected the flow switch. Looks good (nothing stuck or obstructing, looks clean). What kind of check can I make to know the flow switch is the problem (before I spend $80.00 on the replacement flow switch)?
