FAULT CODES AND POOR PERFORMANCE

Faults are displayed on the LCD (not fitted on integrated or flat door models) and on the touch switch panel.
There are ten F (fatal) faults, which are displayed along with a spanner in the LCD (if fitted).
An F fault will usually require the assistance of a qualified service person.
In addition, there are 4 U (user) faults.
U1 is displayed on the LCD as a "no tap" symbol. U2 is restricted lid travel.
The customer can usually rectify a U1 or U2 fault.
U3 fault is not displayed to the customer, but is recorded in the fault history and displayed on the Smart Tool.
It is logged if the motor senses primes in less than 20 seconds because water was left in the tub from a previous fill, or
because it has filled too quickly. The product will drain and refill up to 5 times before logging the fault and continuing on
with the cycle.
A U4 fault indicates an F fault with the other tub that has disabled the power supply.
In the integrated and flat 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.
Once a fault is repaired, it can be cleared by pressing the POWER button. If the fault is still present, then it will not clear.
A fatal or user fault is accompanied by a continuous pulsating beep, which can be turned off by pressing the POWER,
START/PAUSE, or KEYLOCK buttons. This also stops the drain pump running for an F1 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.
Except for U4, F1, F3, F8 and F9, the other tub can still be used on a double product.
Once the fault has been cleared for an F3, F8 or F9 fault, the power needs to be disconnected and reconnected to reset
the isolation relay before the product can be used again.
