Problem Possible cause Remedy The w indicator starts flashing before the start of a programme. The programme cannot be started. Before trying to rectify the problem, you must: – Turn the programme selector to f (the fault code goes out). – Switch the machine off with the I-0 switch.
Problem Possible cause Remedy The Add salt indicator light k flashes. The salt reservoir has not been replenished, meaning that the water softener could not be reactivated. Fill carefully with salt. A few minutes after the start of a programme, the p / 6 indicator flashes and the programme is cancelled.
Problem Possible cause Remedy The programme is cancelled and the p / 6 indicator flashes. Before trying to rectify the problem, you must: – Turn the programme selector to f (the fault code goes out). – Switch the machine off with the I-0 switch. Fault code: F.
Problem Possible cause Remedy Cleaning agent residue is left in the dispenser for powder cleaning agent at the end of a programme. – Remove the residue. – Run the process again. The dispenser for powder cleaning agent was still damp when it was filled.
Problem Possible cause Remedy Glass utensils are cloudy and etched. The items are not suitable for machine processing. Only clean instruments that are suitable for machine processing in the machine. Neutralisation has not been carried out during the programme cycle.
Problem Possible cause Remedy White residues and/or flecks are visible on items. The water softener is programmed to a setting which is too low. Check the water hardness level of the water supply and programme the water softener correctly. Water entering the machine through the AD water connection is not soft enough.
Problem Possible cause Remedy The cleaning result is unsatisfactory. Baskets or inserts have been incorrectly loaded or overloaded. Rearrange the items. Do not overload baskets or inserts. The programme selected is not suitable for the degree of soiling.
Thermal cut-out This machine has a resettable heater limiter which will shut off the elements in the event of over-heating. This could be caused, for example, by large articles covering the heating elements or if the filters in the wash cabinet are blocked.
