3.7.2 Dispensing Detergent and Rinse Aid
The dispenser is mounted in the front of the wash tub, and is held in place with 2 brackets and 6 torx screws.
The dispenser consists of two detergent chambers, the smaller one for the pre rinse and the larger one is the main wash bucket.
The detergent dispenser door is opened manually to fill the detergent bucket, and closed manually.
There is a positive displacement pump unit and storage tank incorporated within the dispenser to supply rinse aid.
The rinse aid volume is adjustable through the option adjustment mode (refer section 4). A glowing red light on the tank filler cap indicates an empty rinse aid tank.
3.7.3 Amount of Water
The tub fills with approximately 2.5 litres (0.8 US gallons) of water, almost level with the base of the spray arm. Once the level is reached, the wash pump (which is load sensed via the electronics) becomes primed and pumps the water through the spray arms causing them to rotate.
The load on the wash pump is continually monitored through the electronics, and the wash level adjusted if necessary.
If the wash pump looses prime, the electronics will top up the water level by opening the fill valve for approx 5 seconds, it will do this 3 times before carrying on regardless.
In low water pressure situations, the product will not reach a prime and may time out. In these cases the product will show a U1 fault code to the customer. (refer section 6).
3.7.4 Flood Protection
A flood sensor is mounted in the mains filter housing, and provides flood protection. If a flood is detected, the drain pump will run continually and an E1 fault code will be signalled to the customer.
