Aquapure 1400 170 187 Error Codes

[Jim.d]

Hi,

My Aquapure has 170 187 error codes. I have already replaced the sensor hoping that would help. Should I start testing voltages next? If so, where can I get a schematic of the boards?

Thanks,

Jim

Welcome to TFP!

Google Jandy AquaPure Workbook and you should find a guide that shows all the steps you need to take to determine which part is failing. There will be a guide that has a flow chart to follow.

With the 170 error it could be the transformer that is bad, but you need to follow all the steps to determine the failure.

Thanks for the info ping!

The workbook helped a bit, but it doesn't reference the same model I have. My PIB is in the Plastic Control Center (APURE1400), not in the main control box. However, I did measure the voltages on the 'back board' with an analog MM and they were as follows: test points 1-8 is 68VAC, should be 75VAC (67-88 is acceptable range I found in workbook), 2-7 is 60 VAC (s/b 60-79), and 3-6 is 18 VAC (s/b 17-24). All are low, but right within range if my meter is accurate. The cell does not turn on so I could not test between pins 4-5.

Are those voltages close enough, or should I replace my transformer?

Thanks again for your time!

The transformer puts out voltage, it appears it is putting out voltage, why would you replace it? There are two points that go to the cell, what are they measuring?

 

[Jim.d]

There is no voltage to the cell. I am assuming that the relay for the cell is not activated due to the error codes.

Is it wired for 120V or 240V?

Measure the incoming voltage? If it is below 108V or 216V the incoming voltage is low.

The PIB or transformer are the 2 things that can be bad if the incoming voltage is good. The transformer barely passed, so that leaves the PIB.

 

[Jim.d]

Incoming voltage is 118. Will be PIB still operate if the voltage is low?
Thanks guys!

 

[Jim.d]

Correction, incoming 112 VAC

It only needs 108V for a system on 120V, so the incoming voltage is enough.

The troubleshooting guide says the PIB is bad, but the voltages are right at the minimum for the transformer. The first thing I would replace would be the PIB, but it's your call on what to do.

Your supposed to make sure its set to chlorinate and then check the voltages coming out of the points for the cell. I had these codes and it was because the connector from the transformer to the board was melted and if I moved the wires slightly it would work. Had to replace both parts because of that. I'd guess its your board. I got my stuff on ebay used. paid about 80 dollars or so for each one.

 

[Jim.d]

I did have the unit set to 100%, but still no voltage to the cell. I replaced the transformer, but still have the 170, 187 error codes. The connectors look OK. So, now on to the boards. As you know, there are two, the 'front' and the 'back'. If I'm to believe there error codes at all, you would think its the back board given that the 187 code says: 'Front board power supply either too low or too high'. Another data point is that the new sensor is set to Program B, but the flow indicator light is not illuminated.

Any insight/ experience on which board to replace?

Thanks again.

I think mine only had one board, I'm guessing yours is a little older than mine.

It's most likely the front board. Click my name and send an email to me, I have an old troubleshooting guide that I have saved that I can send to you in an email.

Part of the flow chart is the following:

Is code 187 displayed with code 170? Yes, Test all test points on back board except from 4 - 5, if they are normal, the front board power supply is either too high or too low. Front board is defective replace front board.
