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). Re-tape with teflon.

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
