Choose what you notice. These are the issues covered by your appliance guide.
Water stays inside or a drain error appears
E:22 · E:24 · E:25
Possible causes
The programme may still be running
What to check
Check the display before opening the filters.
Wait for programme end, or hold Start/Reset for about 3 seconds to cancel, then wait about 1 minute.
Filters or the pump may be blocked
What to check
Check and clean the filters first, then the pump if drainage is still blocked.
The drain hose or siphon connection may be blocked
What to check
Look for a kink or obstruction in the drain hose.
Have an inaccessible blockage or closed siphon connection corrected by the installer. Ensure the pump cover has clicked shut.
The dishwasher cannot fill
E:18
Possible causes
The tap or hose may restrict water
What to check
Check that the tap is open and the inlet hose is not kinked.
The supply must provide at least 10 litres per minute. Have a blocked or scaled tap checked if the flow is too low.
Water protection or continuous filling needs service
E:14 · E:15 · E:16
Possible causes
Water protection is active or water keeps entering
What to check
Close the tap.
Contact customer service and report the code. Do not keep restarting the dishwasher.
An electrical or recurring technical error appears
E:27
Possible causes
E:27 indicates low mains voltage
What to check
Do not attempt electrical repairs.
Have an electrician check the mains supply and electrical installation.
Another technical error recurs
What to check
Note the displayed code.
For another technical error, switch off, unplug or isolate the fuse, wait at least 2 minutes, reconnect and switch on. If it recurs, switch off, close the tap, unplug and contact service with the code.
Dishes stay dirty or detergent remains
Possible causes
Spray arms, filters or loading may obstruct washing
What to check
Check that spray arms turn freely, filters are clean and the tablet collecting tray is clear.
Load dishes so water reaches them and put detergent only in a dry dispenser.
The tub has grease or deposits
Dishes stay wet, streaked or marked
Possible causes
Rinse aid is missing or incorrectly dosed
White deposits may indicate a hardness mismatch
Water can collect in hollows or a programme may have no drying stage
What to check
Arrange hollow items at an angle and choose a programme with drying.
Plastic can retain more water than other materials. Do not block the Zeolith intake.
There is excessive foam
Possible causes
Rinse aid spills or an unsuitable product may foam
What to check
Check for spilled rinse aid and the product used.
Wipe up spilled rinse aid. Use dishwasher products, never hand-washing detergent. If a cleaning product foams excessively, change to a suitable product.
A Zeolith intake or scaling error appears
E:07 · E:12
Possible causes
Dishes cover the Zeolith intake
What to check
Check the intake opening is clear.
Reposition dishes so the intake opening is unobstructed.
The heater is scaled
What to check
Check the water-softener setting.
Ask Siemens for the applicable descaling product and its instructions. Do not improvise an acid quantity or cycle.
