Solutions |
| 1. Pressure inside the Chamber can be relieved by pulling on the ring of the Safety Relief Valve. **** Caution **** Be careful not to position your head over the valve. This can result in a severe burn. Empty any water from inside the Chamber Open the Exhaust Valve and check for any debris that may be causing the Plunger to be stuck closed. Blow compressed air from the Valve Base through tubes going to the Chamber and the Water Reservoir. This will clean out any clogs that may have developed. If the tubing remains clogged then remove it and clean it manually or replace it. On units manufactured after 2/2000 open the Chamber Strainer to check for clogs. When blowing compressed air, blow from the Exhaust Valve Base to the Chamber Strainer then from the Chamber Strainer to the Chamber. Reassemble all components previously dissembled. Turn the unit on and start a Dry only cycle. |
| 2. *** Caution the Heating Elements will come on. *** During the Dry mode the Exhaust Valve should be open Check between TP11 and TP1 a DC voltage of 0 to 1 volt tells the valve to open and 10 to 12 volts tells it to close. If TP11 is between 0 to 1 volt and the valve is closed then check for a loose connector or broken orange or black wire going from the solenoid to the Electronic Box Remove the Solenoid Coil and check across the terminals for a short Remove the connection box from the Solenoid Coil and check that the connectors are in place and making good contact with the terminals on the Solenoid Coil. Check if the Solenoid Coil has received the proper signal Take apart the Plunger Assembly and clean any debris that may be stopping the Plunger from sliding back and forth. Check the housing of the Plunger for any nicks or distortions that can cause the Plunger to become stuck. |
