6 FAULT CODES AND POOR PERFORMANCE
Faults are displayed on the LCD (if tted) and are also displayed on the touch switch panel for the
integrated and at door models and remote badge models.
There are 10 “E” fault codes, which are displayed along with a spanner in the LCD (if tted). Within the
E fault are sub code faults, which help identify the failure mode and provide more information. ( refer
page 38 & 39 for sub codes)
An E fault will usually require the assistance of a qualied service person.
In addition, there are 3 U (user) faults.
U1 is displayed on the LCD as a “no tap” symbol. (time out on ll is after 175 seconds)
The customer can usually rectify a U1 fault.
A U4 fault indicates an E fault with the other tub that has disabled the power supply, it will only be
displayed when the START/PAUSE button is pressed.
In the integrated and at door models, where an LCD is not available, the presence of a fault is indicated
by a red centre (Start/Pause) LED on the badge, with the fault number indicated by the Red LEDs on the
touch switch panel.
A U6 indicates that the spray arm may have become dislodged from the rotor, or, the water supply
pressure to the product is too low. (time out on ll is after 175 seconds)
Model Maximum Water Pressure Minimum Water Pressure
water softener model 1 MPa 0.1 MPa (14.5 psi)
non water softener model 1 MPa 0.03MPa (4.3 psi)
Once a user fault is repaired, it can be cleared by pressing the POWER button. If the fault is still present,
then it will not clear.
An E fault or user fault is accompanied by a continuous pulsating beep, which can be turned o by
pressing the KEYLOCK button. This also stops the drain pump running for an E1 fault.
The last two faults are logged into EE memory.
If a tub is forced open, the product simply pauses as if someone had pressed the start/pause button.
Once the fault has been cleared, the power needs to be disconnected and reconnected to reset the
isolation relay before the product can be used again.
