Replace or repair Hayward pro logic PCB control board

[westhart]

I have a Hayward pro logic PCB and the date and time function doesn’t keep time. It works when I set it but hours later it is wrong. I have read volume about how to fix the time/date function on the board. Also read about people sending their boards off for repair. Everything else is working on the board (manually). The wireless remote will not pair to the board although we have only had it two years. Again tried everything to fix it. Even put it in the frig?!
First question :
Can the date time function on the board be fixed? (I have taken the board out before and am comfortable replacing parts )

Welcome to TFP.

Can the date time function on the board be fixed? Sure.

Does anyone here know what components need to be replaced to fix it? Try here --> Hayward Aqualogic - Further Reading

The clock does not keep proper time.[7]

A thread on this board repair can be found at Hayward ECommand not keeping time: updated DIY repair guide.

You can replace the board or try repairing the board. On the board it has a capacitor on the left top corner, it's like a double battery in wrap. You can buy on Ebay for about $3 and 5 mins to replace it. After replacement you run for 1 hr it will charge the battery.[8]

On the board:

• U1-Microprocessor is PIC18F2620 (28 pin version)
• U2-Real Time Clock is Dallas / Maxim RTC is $3.50 at Digikey (DS1302Z+CT-ND)
• C3-Super Cap is 5v and .33UF Digi-Key KR-5R5V334-R
• X2-is a 32.768 kHz Crystal Epson MC-306 / 6 pF (SER4099CT-ND at Digikey) and costs $.046

Some people replaced just the C3 capacitor, others repalced C3 and X2, and others replaced U2, X2 and C3.[9] Replacing U2 and X2 is not an easy soldering job if you are not used to surface mount parts, don't try it.

After replacing parts you need to wait about 24 hours for the real time clock to start working and then adjusting it to current time.

REPAIRED! - Hayward GLX-PCB-MAIN

For the 4th time in 12 years, the main control board on my Hayward pool system went out (the board is Hayward GLX-PCB-MAIN). Each time the board lasts 2.5 - 3 years so it is out of warranty. Each time the symptoms have been the clock not keeping time and as a result, the pool cycle starts at a...
