Your wash arm has a magnet in the end, on outside of the tub there is a sensor that senses the magnetic field every time the arm passes by it. It sends this signal to the processor which counts the passes and computes the revolutions per minute.
Should these be outside of the accepted parameters it will shut down the dishwasher and the alarm will go off. I usually try to start with the simplest things first. I doubt very much the magnet has come detached, but it's not impossible. If you rotate your wash tower (I I remember correctly, counter clockwise, but try both ways, it will unscrew. Below is a Philips head screw that you can remove then lift off your wash arm. Do not lose the bearing and washer. You can shake the arm lightly and see if you can hear the magnet moving around. Check your sensor, at the wash arm level on the outside of the tub and make sure that the wires are attached. Follow the wires through the harness and make sure there is no damage and that they are connected to the terminal block on the path and termination at the control board. I once had a GSD 1200 where the bearing was worn and it occasionally touched the side of the tub, and wobbled a bit. It could be your "orbit" is more eccentric due to a worn bearing and possibly the magnet is not getting close enough to the sensor. These are my first thoughts to check. Others may have some ideas. Unless it has been removed, you have a document package located underneath the tub and the frame member of your dishwasher, on the right hand side. It's in a small paper envelope/packet. Remove the lower front panel and look for it. GE places it there, and it has a schematic, cycle information, and ways to troubleshoot problems in both the mechanical portions of your machine as well as the the electronics. It's ver useful. There are diagnostic tools built into your processor for the service man. This packet will show you have to implement these. Unfortunately, mine seem to have vanished or I could help you more. |

Until you can find and fix the problem you can override the alarms and run your dishwasher. I think you hit it the start button twice in succession but I can't remember exactly. It seems like two times within two seconds. I used to do it all the time when my detergent door sensor would shut down the machine..but it's
been years. Your information packet will tell you. But the good thing is you can keep using your machine. |

In some GSD2800 sensors.*
It can be replaced with a generic one, such as Technics used in their 1980s/90s cassette decks. But - it's more likely that was, indeed, your magnet. Can you post some pics? We might be able to point to the part of the arm you unscrew. *Some had a HALL sensor, but we've had three and they all were reed. GE learned by doing in that era. Before they stopped learning. |

My parents bought that new in 1985 for their new home. It lasted until 1999 when it was switched out for a KA Superba, but it was still working. I don't even remember seeing any rust on the racks though it did have a quiet squeal every time the wash arm hit a certain spot in it's revolution.
