Summit washer/dryer combo quit drying. Repairman came and replaced themafuse and thermastat kit. Shortly thereafter, the dryer cycle timer would indicate 10 minutes left and never clock down. The dryer would have to be manually shut off or would continue to dry without stopping. Also heavier clothes like jeans would not completely dry as before. Needed several cycles. Repairman returned and said he would have to contact Summit. After he ran a short heat cycle 20 minutes, the machine is not stuck and not usuable. The error message H Loc is flashing, the red light indicator for the closed ,door is on and yet you can open the door, the standard indicator red light is on, the water level light is on, and yet you cannot power the machine off or on, or start it back up. It is stuck. The repairman told me to unplug the machine and let it sit for 30 minutes and plug it back in to reset it. Well this did nothing, This unit is in a rental condo and is not working for the renter or us the owners. Called the repairman back and told him I cannot get the machine working again after he was here. He said he would have to talk with Summit. He is the suggested Summit repairman for this area. He only services this area two days a week and I have to take off work to get this unit worked on. Any advice on what could have happened since the machine worked last night, washed and dried -- just would not turn off once the time indicator reached 10 minutes -- stayed at 10 minutes. The repairman did open the top of the unit to make sure the blower was working. Other than that and letting the dryer operate for a period of 20 minutes, he did nothing else.
