Bosch 500 series washer error e 13

If cleaning the debris trap doesn't work and if you're handy you can try this. My problem was intermittent and E 13 code. UNPLUG MACHINE!!! With a shop vac, remove water from debris trap or any method at your disposal, a wet/dry vac works slick. Turn off water supplies and remove from back of the machine. Disconnect drain pipe and move washer to where you can lay it on it's side. Remove back panel, about 20 torx screws. Remove top panel, 2 torx screws and gently lift from rear and pull to remove. From the rear view the pump is on the bottom behind the debris trap. Wedge a towel between the drum and the right side of the machine so drum is supported when the machine is on its side. With help if needed, lay the machine on it's side so the pump is on the high side and towel on the bottom (this sucker is heavy). Remove plug from back of pump by pressing clip and gently pull off. I removed what looks a large rubber manifold, 2 spring clamps and one hose clamp. Note the inserts on this part that Bosch made so that when you put it back together all the parts line up. I thoroughly cleaned this part on the inside and found lots of debris that would eventually get to the debris trap. Disconnect the drain tube from the machine and not the pump. Remove pump, debris trap and drain hose as a unit by pushing and sliding the 4 rubber stabilizer pads on bottom of machine. Carefully pull out as a unit and stay away from wires that you encounter. BE PATIENT! Disconnect hose from pump by pushing the small inserts and gently pulling. Mark where the pump meets the debris trap so it goes back on in the same spot. By hand, gently push the pump against the trap and turn counterclockwise about a half inch and the parts will come apart. My problem turned out to be gunk in the pump itself. Pull impeller from pump assembly and note the rubber O ring, don't damage it! These parts are spring loaded and should separate easily. I cleaned the pump parts in the kitchen sink with hot water then outside with brake cleaner to remove all the gunk. I siliconed the O ring as it was not damaged (don't know where I would get a replacement). Thoroughly clean the pump and don't get the motor wet. I was amazed at the sludge that came out, no wonder it didn't work! Now would be the time to replace the pump if needed. That's up to you. Put it all back together and be patient with the rubber manifold noting the inserts. Do the spring clamp on the pump first, the machine drain next then the large manifold hose clamp last. I swore a lot but got it done. The drain hose can be easily installed anytime. The machine works like new now. If cleaning the debris trap doesn't work and if you're handy you can try this.
