I am running a 3 1/2 year old Aquapure 1400 and have been getting codes 120 & 121. Chlorine production seems to have decreased. Deposits build up quickly inside the cell, and despite frequent cleaning, the codes persist.
In an effort to figure out what is going on, I did the test procedures outlined in this file:
http://www.pleasurepoolsno.com/wp-conte ... Manual.pdf. Here's the results:
Front Board Firmware rev# 112305A
Back Board Rev. 8 B10032-08A
Back Board Transformer Voltages
test points 1-8 76.6 VAC (should be 75 VAC)
test points 2-7 66.6 VAC (should be 65 VAC)
test points 3-6 20.97 VAC (should be 21 VAC)
test points 4-5 51.5 mVDC (should be 120 mVDC)
Cell Voltage 35.5 VDC (should be 22 - 28) tested at Back Board test points
Cell Voltage 34.95 VDC tested at cell
Front Board Current Test (w/ cell on)
test points H-K 49.1 mVDC (should be 120 mVDC)
test points A-C 20.9 VAC (should be 21 VAC)
Salinity test button 2.8 GPL (should be 2. GPL)
R Temp test button 74 (should be 75)
H Temp test button 91 (should be 91)
Now that I have this information, I really don't know what it means.
Do I have a transformer problem? A board problem? A cell problem?
Any help with this would be greatly appreciated.
