Question about Bosch 24 in. SGS43C12 Classixx Free-Standing Dishwasher
The check water light is on and the dishwasher is not draining. we have emptied the dishwasher manually and cleaned the filter. It seems blocked some where inside the dishwasher. What can i do?
I had the same problem! First disconnect mains power, then switch off the mains water to the water input hose, and disconnect the hose. Disconnect the waste outlet hose from your drainage. ( this will release some water from the hose ends, so a washing up bowl would be handy ) You will need to tip the dishwasher on to it's back, be carefull not to damage the waste outlet hose, and watch out from more water spillage. Next remove the two screws on the base metal cover, and spring out the cover from the two side clips, the cover can then be removed, you should have a screw holding an earth lead remove screw and lead from cover.
Inside the bottom of the dishwasher you will see a small electric pump fitted to the side of the dishwashers drain, it has two wires with spade connector on them, disconnect these from the pump noting colour of the wires for reassembling. The pump has the same diameter hose as the outlet hose. Next carefully remove the rubber elbow pipe from the pump and hose end this will need to be washed with clean water. Then to remove the pump, press and hold down the locking tab, where the pump is fitted to the drain, and twist the pump anti-clockwise. The pump will then release from the drain. Inspect the pump impellers for damage, and that the pump has free movement, also check condition of the rubber O-ring. Inspect inside of drain for broken bits of china and glass, remove and clean, also check the outlet hose for any blockages.
( run some water though the hose backwards from the water tap and collect it in a bowl from the pump end of the hose ) Reassembly is the reverse of the above, check electrics inside have not got wet, if ok switch on. The check water light should now be off.

This draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. First make sure that the drain is not clogged and remove clogs if present. If no visible lint is present then remove the lower front access panel to check the drain filter and drain pump for any clogs, you'll need to clean the drain filter and drain pump completely. Also, check for any food pieces stuck near the pump impeller & clean the chopper assembly. Please note that dishwashers don't drain out the complete water such that heating element doesn't overheat. Hope this helps... Please post back for any further assistance.
