Thanks Swamprat, used the hayward guide and replaced PCB. No codes anymore.

Its H400IDL2, just updated the title with full model number. No opened both panels from front and no sing of any wire damages.

Hi experts, I have SF code on my pool heater and have done this so far but error code is not going away. 1. Replaced thermistor FDXLTER1930 twice thinking maybe a wrong thermistor. 2. Disconnect/Connect limit switches. 3. Disconnect/Connect PCB wires. Want to do hard reset of PCB to remove...

Would like to get opinion on bypassing (jumping) relay before getting $600 board since K2 or K3 relays are the suspect. Has anyone tried jumping and taking out the relays from circuit ? Any EEs advice ?

Thanks James. Oouch, $300+ for the circuit board.

Tried pressing - and + buttons in diagnostic menu, hear the click in the board but salt level is always 0000. Tried the side arrow button to save the instant salinity but that is also always 0000.

Since last three days salt level is reading 0. Y Tried to resolder all 3 relays, however no luck on getting correct salt level. Any other things can be tried other than replacing board

25.6 V 6.47A 83F 3100 stayed that for about 3 hours now. yes tried Neighbour’s cell made no difference. any down side if continued like this.

Thanks ajw22. Resoldered both K2 and K3 burnt connections. System did read the salt values but after about a minute goes down to 2600 and same error again. During diagnosis, saves instant salt level to 3100 as soon as it trickled down to that. Been working for about 10 minutes. Is this safe to...

I see K2 and K3 relay burnt which is new, as you see in the picture. Should just resoldering might help getting the issue resolved or replace the K2 and K3 relay is required.

Any update on the salt cell issue, experiencing similar issue on mine.

Thanks for quick response. Don’t have the option of switch selections in aqua logic system. Below are the readings. 31.5V -0.00A 81 F 0000 PPM - Cell serial number : 3E13149 - took sample to Leslies and they provided the readings of 3500. I have the kit but store is almost Nextdoor so been...

Ok
