9-2. Troubleshooting for Steam Dryer PROBLEM SOLUTIONS POSSIBLE CAUSES This is steam condensation. Water drips from nozzle This is normal. The dripping water will stop after a short time. when Steam Cycle starts. The drum does not turn The drum is turned off and only tumbles This is normal.
DIAGNOSTIC TEST 1. This TEST should be used for Factory test /Service test. Do not use this DIAGNOSTIC TEST other than specified. 2. Activating the Heater manually with the Door open may trip the Thermostat attached to the Heater, therefore do not activate it manually.
Test 1 120V AC Electrical supply NOTE: To properly check power supply in case of floating neutral or high resistance connections, a load must be applied to the circuit. It is important that the power button be pressed while checking the voltages as described below. With the dryer plugged in, press the POWER button to turn on dryer.
When measuring power, be sure to wear insulated gloves, to and avoid an Caution electric shock. Trouble Symptom Check the Tab Relays Connection properly.
