TROUBLESHOOTING GUIDE (cont’d) Symptom 4: Discharge pump continually runs while in the auto mode. Step A ✤ Confirm the low-level float is not adjusted too low within the holding tank. This float should be at least 1.5" above the bottom of the holding tank. This assures the float will be positioned above both the residual fluid level and the dip tube opening. If not positioned correctly, the low float will never drop down and trigger the discharge pump to shut off.
If reading is equal to the control voltage, go to step C. ¾ If reading is less than the control voltage, check for the following. Defective DC power supply and/or defective electrical connections in main power line Blown fuse or tripped circuit breaker Step C Follow all troubleshooting steps for Symptom 1 and Symptom 2.
