Error Code on Heater / how to resolve

[tstex]

My Hayward H440FD has an error code of Sb, which is indicated in the enclosed pic. The Service light is also lit.

The error code for Sb states:

Keypad button stuck closed error=If one of the keypad buttons is closed (or pressed) for more than 30 s the error code will be displayed but the control will continue to function. The error code will be cleared when the condition is corrected.

Does anyone knows how to correct “this condition?” If you have any questions, pls let me know? I’m running my heater now bc it’s 58 degrees and nice time to do so.

Thank you
Tstex

Probably needs a new keypad.

Unplug the keypad to see if the error goes away.

Well, I am sure that is not going to be cheap...is there anyway to reset it?

I'm heating my spa and the heater seems to be working fine and doing it job...it started at 64 degrees and is 80 now...

When was the heater made (S/N)?

Thank you very much James !!

I'm using the heater now so I cannot diagnose anything. Once it cools down, I will turn-off circuit breaker to heater, then unplug to see if it resets. If not, then I'm buying a new keypad.

Also, when looking online for parts, I saw where you can replace the whole circuit board which includes the keypad. Is there a way to determine if its something else other than the keypad? I know the S5 error alludes to keypad, but I have seen crazier things.

Thanks again James, tstex

Unplug the keypad from the circuit board. If the problem goes away, the keypad is bad.

IF I unplug the keypad from c-board, won't the keypad screen go completely blank? then don't reconnect the key pad and wait to see what the keypad says after I turn the power back on? Am I interpreting this correctly?

Note, I have a H400FD heater, which I erroneously had H440FD but corrected via edit. Also, most of the parts for the H Series heater are for an H400FDN. Does this add'l "N" have any bearing on part compatibility? Thanks again

No, the display comes from the display board. The keypad is just a clear window.

On the left hand side, you can see the E2 (4) pin connector labeled keypad. Disconnect the ribbon cable that's going from the keypad to the (4) pin connector.

The N just means Natural gas. The only parts affected are the gas valve and orifices, which can be natural gas or propane. The other parts are the same.

My control panel failed after a year, I bought a keyboard at first but ended up buying the whole unit. Seems like it was around $100 which is what Hayward wanted to charge for a service call.
Its an easy swap, my heater is about 6 years old and seeing James reply maybe they improved then around 2014. Replacement seems to be holding up.

 

[tstex]

Thanks Mark. Mine was installed around Oct 2014...I’m going to test the display like James said.
If yours was only a yr old, didn’t you have a 3yr warranty? Electronics these days are not built to last long...sad but true.

 

[markayash]

They said “ maybe covered” but wanted to charge a service charge to check it or around $100. I installed the new er myself and fiq they would blame me so just ordered the part .

When was the heater made (S/N)?

Good Morning James and all,

My serial no is (21) 131310102613001 From my research, the heater was made in 310 or Oct 2013. If that's correct, is that typical of a Nov 2014 install? That was a 13 months old when installed ?

Either way, is this what I need to do to test the keypad to see if the error code goes away.
-turn off circuit/breaker to heater
-remove the four screws that holds in the keypad to heater framing
-detach the appropriate pieces that connect the circuit board to heater
-remove screws that hold key pad to circuit board as shown in video
-disconnect keypad ribbon cord from circuit board

Questions:

At this point, do I reverse everything and see if disconnecting keypad can be reset and works or do i put back together w out re-plugging in ribbon cord to c-board to see if error code goes away as you stated? For the latter, do I need to do anything to the keypad?

On the latter, to determine if the keypad is bad after unplugging, what am I looking for [or not looking for]?

Is/Are the process(es) above correct?

Thank you very much.

That's what I bought, thinking back I tried to buy a cheaper kit and it didn't work but this fix it..
Also Amazon has it for a lot cheaper.

Just disconnect the keypad ribbon cable from the display board. If the "Stuck Button" error goes away, the keypad is defective.

Thanks for clarification - I'm on it and will post back...thanks

That was EZ-PZ..sorry for complicating an ez process.....it is keypad bc the "bo" light came on as it should when VSP is running at low speed...

Note, I can still use the heater via my remote or control panel, it's just that the keypad is non-functional, correct? Thanks again, tstex
