Problem Solving
Symtom | Solution | |
Unit filling to low level but not heating | 1. | Possible faulty PCB |
| 2. | Check Element |
| 3. | Check all wiring connections |
Unit not filling | 1. | Check top probe (No.11 page 3) and ensure that the |
|
| probe is not in contact with tubing. Also check for |
|
| scale build up. |
| 2. | Check solenoid valve (No.1 page 3) with multimeter |
|
| set to K Ohms scale, it should read between |
|
| 3.9 - 4.2. |
| 3. | Check water supply. |
| 4. Turn pwer supply on then off to see if you can hear | |
|
| the “squirt” of water from the solenoid valve. |
Unit continually boiling | 1. | Replace thermistor steam sensor (No.4 page 3) |
| 2. | If above does not solve problem, replace PCB |
|
| (No.15a or 15b page 3). |
| 3. | Check the thermistor is positioned correctly. |
Manual reset thermostat |
|
|
(Unscrew) | 1. | Check water supply to tank. |
(Element boil dry protection) | 2. | Check element. |
| 3. | Replace manual reset. |
Tap leaking | 1. | Replace tap cup seal (No.15 page 3) |
| 2. | Replace tap assy (No.9 page 3). |
Unit slow in “Heat/Fill” cycle | 1. Water transfer hole in the cold water supply tube | |
|
| may be blocked. Check and clear blockage. |
( the hole is positioned above the thermistor sensing probe, linking the cold supply and condensor tubes)
NOTE: Ensure all Earth connections are secure, failure to do so will cause the unit to operate irratically
