CDT845M5N2S5 General Electric Dishwasher - Instructions

Decided it could be 1 of 3 things. Fuse on main circuit board that controls hot water. Main control board or drain pump failure. Was not able to find out how to do diagnostics on this unit as there is no "cycle control" feature and this is a top of the line unit. Replaced the fuse and dishwasher failed. Replaced the circuit board and dishwasher failed the first time. Second time it went to completion and has worked properly since. You can go on line and find videos on removing the circuit board for GE dishwashers. This can be done without pulling the dishwasher out. Remove the lower black dust panel and insulation. Remove cover to electrical box - 1 screw and remove. Remove 2 to 4 screw on a sheet metal bracket that holds the circuit board. Notice where 2 metal hangers are located if you remove 4 screws on the left and right side of machine as they drop out. Remove black corded door sensor under circuit board. Work the sheet metal back and forth to remove from dish washer so that circuit board is exposed. Remove circuit board connectors and pull out unit to install new circuit board. Some have one screw and some have only plastic retainers. Re-install. I did not need the drain pump and the circuit board comes with a control board fuse. Washer was only 14 months old and 2 months out of warranty.

Replaced floating seal. Un plugged and Pulled washer out from the counter and laid on its left side. Pull pump out of seal by hand. Straight screwdriver to lever seal out of fitting. Clean hole and wipe seal then push into hole. Reinsert pump reverse install.
To make it easier I previously extended the water supply hose to nearly 8 feet so did not have to disconnect it.

Process of elimination and a visit to my local repair store told me it was wise to try the tub gasket, and according to partselect.com, it solved the problem a majority of the time. My local repair dealer agreed: Try it. They agreed because for them to replace a lower door gasket AND the $10 tub gasket... if they came out, the service call and parts would equal half the cost to replace the whole dishwasher. So I bought a tub gasket from partselect.com and replaced the old one. It worked, it was easy, so if your same make & model is leaking? Try it first. That's my advice.

Replaced old gasket with new one. More difficult than expected, because new gasket was much stiffer than old one. Also, the yellow centering spot on gasket (to line up with top latch) was nearly impossible to see. Unfortunately, this did not solve the problem for me, so money was wasted. Bought new dishwasher.

Bottom rack came complete with all racks. Only had to transfer the (2) side bumper guards,

Simply removed old gasket by hand, lined up center of new gasket (white dot was printed on the center of new gasket) with the tub latch and pressed new gasket into place. We have used the dishwasher about a dozen times since and hasn't leaked a drop.

When new gasket arrived almost two weeks after it was sent out from Green Bay, I took out old gasket, marking which side was in and which out.
Then, with hands, fit new gasket in place making sure it was centered.
No leaking; it worked.
Thanks.

the actual gasket tub seal was easy, 10 minutes. The trim tub gaskets were a pain because I had to uninstall the dishwasher (not plumbing or electrical) then pull it out from the cabinet, remove old trim and re-install. Re-leveled dishwasher, screwed into side of cabinets but it still leaks. Can't figure out where but after replacing all the trim and gaskets its very frustrating.

Remove top rack stops, slide out upper rack from rack railing, turn over upper rack and attach spray arm using spray arm bearing and screw. Reassemble in reverse order.
