Jons laundromat Posted October 27, 2020 Share Posted October 27, 2020 I have a 6600 that has worked well for years. Something happened to it and it lost power to the key pad. Got a new main board. Now the key pad is working but keeps resetting I.e. prices back to default, shows $12.65 credit and then kicks out the change. Any ideas on what could be the issue?

orsd Posted October 28, 2020 Share Posted October 28, 2020 Look for burned out dim or flickering fluorescent light bulbs in and around the machine. They throw off massive amounts of electromagnetic interference trying to start and it scrambles the boards temporarily. Link to comment Share on other sites More sharing options...
Jons laundromat Posted November 21, 2020 Author Share Posted November 21, 2020 Thanks. I actully didn’t think that was going to do anything. But I didn’t have anything else to go with and the light in the machine was flickering. Took the bulb out and haven’t had a problem since. I was talking with a guy about a week ago who owns an electrical company and he explained it. Thanks again. Really appreciate the help. Link to comment Share on other sites More sharing options...
