2. Valve in regeneration 2. Wait until regeneration finishes or advance regeneration to end
3. Loss of resin 3. Refer to problem “Loss of resin”
4. Mixing valve open 4. Reduce mixing valve opening
5. Change in raw water hardness 5. Adjust programming accordingly
6. Unit fails to regenerate 6. Refer to problem “Unit fails to regenerate”
7. Valve fails to draw brine 7. Refer to problem “Valve fails to draw brine”
8. Decreasing exchange capacity of resin 8. Clean or replace resin bed
9. No salt in brine tank 9. Add salt
10. Leak at riser tube 10. Verify that riser tube is seated correctly and is not cracked
Unit fails to regenerate
Cause Solution
1. Faulty electrical supply 1. Verify electrical service (fuse, transformer,...)
