Hi, I have a 14 year old Bosh WTL 5500. It has been brilliant but it now refuses to complete the usual program I use: cottons, lightly dry. It stops after a few minutes leaving the washing wet. Cottons, cup board dry works fine but leaves the washing too dry, so I don't like using it. Do you think this would be economical to repair? Thanks IR

Hi Vince!

Your owners manual should tell you what that pair of flashing lights mean, but I suspect it is because the system that detects water level has become clogged with debris and the DW is telling you it refuses to proceed without an accurate water level reading.

Level measurement systems vary but are usually in a float chamber on the side of the unit. Search for an "exploded" view (usually available at part supplier sites) for more 411.

Have you cleaner the filter???

use multi meter and check moister sensor, cycling and hi limit thermostat lastly if it runs about 25 minutes then stops and need about an hour b4 it will start agin? u have bad motor windings

there is a thermal reset button at the back of the unit on the heating element. to get to it you have to remove the back panel that covers the heating element. (its the panel that sticks out). Once that panel is removed you will see the red thermal reset button. press it so it clicks, then start unit. Let me know what happens.

Are you using a rinse aid? if so and teh dishes are still not drying properly, try adjusting the setting for the rinse aid dispenser. Open the door of the dishwasher, open the flap where you pour in the rinse aid and look for the cirlce with the arrow and nunbers on it. If it is set low (1 or 2) try turning the arrow to a higher number. If that adjustment doesn't work, increase again and again until the dishes are dry.

I have the same problem, the dial to select the dry program is making a bad contact causing it to stop. Try using a different program.

I tried to clean the dial but it didn't help.

Please try to wet your fingers a little bit.
When your fingers are dry the ewi would not react properly.

Did you ever get an answer? I have the same problem...

yes if its plastic just pop it out to replace

have you checked the vent line it could be stopped up if the line is bent same affect as the lint filter being full
