Symptom
Unit makes ice, but very slowly
Water leak.
Possible Cause
•High discharge pressure because of a dirty condenser.
•Low capacity because the auger and evaporator are coated with mineral scale.
•Low suction pressure due to low refrigerant charge.
•Drain plugged up.
•Tubing cracked
•Condensation on drain tubing.
•Water hose off
•Reservoir cover off.
•Reservoir cracked.
•Evaporator water seal leaks.
Probable Correction
•Clean filter and condenser.
•Clean the water system.
•Locate leak. Recover the refrigerant, repair leak, replace drier, evacuate and weigh
in the nameplate charge.
•Clean out drain.
•Replace tubing.
•Insulate tubing.
•Reattach hose.
•Return cover to reservoir.
•Replace reservoir.
•Check base of evaporator and drip pan. If the seal leaks, shut off the water, remove the auger and replace the water seal.
Check the gear motor for water infiltration.
