Page 8: Component Description
COMPONENT DESCRIPTION Fill Valve The appliance has an electromagnetically operated solenoid valve, which is connected to the water supply. As the machine fills, a quantity of water is diverted into the fill tank for later use in the regeneration sequence. A typical fill sequence is as follows: The water turbine fills the dishwasher with 2 litres of water. - Page 9 Turbidity Sensor Situated in the hose between the circulation motor and heater. It consists of an infrared transmitter and receiver and it has two function within the dishwasher, identifying the soil level and the presence of rinse aid. The analogue value it produces is sent to the control module for processing. During a cycle, e.g.
- Page 10 Turbo Dry Fan & Condenser - Fitted to models before Serial Number 50214.0000 Mounted on the right hand side of the dishwasher, consisting of a condenser and fan. The fan creates a vacuum in the condensation chamber by sucking dry air (30% RH) from the side of the dishwasher and moist air (100%RH) from inside the dishwasher tub.
- Page 11 Rinse Aid Warning Indicator Situated next to the salt indicator, illuminates when the rinse aid reservoir requires refilling. The turbidity sensor achieves the detection of rinse aid, utilising the same principle as soil level detection. The final rinse water is measured 5 seconds before the rinse aid is dispensed and another reading is taken 1 minute after the rinse aid has been dispensed, The two readings are compared.

Page 15: Installation Instructions
INSTALLATION INSTRUCTIONS Choose where you want to install your dishwasher, you can even place it so that its sides or back panel are side by side with furniture or up against the wall. The dishwasher is provided with water supply and drain hoses, which can be directed towards the left or right to facilitate appropriate installation. - Page 16 SERVICING NOTES & DISMANTLING INSTRUCTIONS SAFETY NOTES:- ENSURE THAT THE MACHINE IS UNPLUGGED BEFORE DISMANTLING.

FAULT CODES & DIAGNOSTICS If an error is detected in programme, the programme will be terminated and one of the following errors will be displayed on the LCD. Fault Fault Possible Cause(s) Code AL 01 Overflow (water in base Leak from water line. pan). - Page 21 Possible Reasons For Fault Code Displayed Note: - Always carry out an earth insulation test before using the fault guide, an earth fault on a component or damaged wiring may display fault codes not related to the component signalled, e.g. an earth fault on the element can display A02.
- Page 22 Time out for filling. The module has not detected turbine rotation with the inlet valve energised. • Check the taps are turned on and that the fill hoses are not kinked. • Check the inlet valve coil (4k ohms approximately) and wiring to valve and edge connector on module.

Page 23: Test Programme
TEST PROGRAMME The following test programme can be used if a fault is suspected within the appliance. There are two test that can be carried out - a 5 minute and a 20 minute test. Each of the two tests performs the same functional check of components with the 20 minute test heating the water to 55°C, verifying the operation of the heater and thermistor. - Page 24 • If the machine has a low resistance to Earth the timer card may become confused and LEDs may not display and the machine may not start. • If a new timer card has been fitted and will not come off the test cycle, check: - 1.
