Problem Title:
Tuttnauer E/EA/EK/EAK Water Fill Problem |
|
Problem Description:
Tuttnauer water flow does not stop |
| Reasons |
| 1. Water filling control is out of order |
|
Solutions |
| 1. Press the Stop button on the Keypad to abort any previous cycle If the water stops flowing then check the Water Sensor If the water does not stop flowing, then turn off power to the machine. If water continues to flow and the unit was manufactured before 2/2000 then the problem is in the Fill Valve. There is debris either on the seat or in the valve stopping it from closing. If the flow of water stops, then turn the unit back on and check the Fill Valve control between TP10 and TP1 for the correct DC volt reading. 0 – 1 volt is open and 10 – 12 volts is closed. If the unit has a Microprocessor dated T97DN7WP or later then check the Water Pump control between TP13 and TP1 for the correct DC volt reading. 0-1 volt the pump is on and 10 – 12 volts the pump is off. If the correct voltages are not seen this would indicate a control problem. If the correct voltages are observed on the test points then check at the solenoid itself for the proper voltages. Also at the Water Pump SSR If the Fill Solenoid or the Water Pump SSR are not receiving the correct control voltages then check the wiring between the connection box or SSR and the back of the Ajunc board for a bad connection. Repair the connection. If the previous connection is good then replace the Ajunc board. |
