Washer water on hot only lukewarm
Don't know whether this question should be in the Appliance or the Plumbing Section.
I have a GE WCSR2090GWW clothes washer. My hot water heater is a tankless set for 120 degrees.
My problem is that the water going into the washing machine is just barely warm even when the washer is set to hot. There seems to be plenty of water flow on the hot setting, so I don't think the water inlet is plugged up with debris. Water going into sinks that are both closer and farther away than the washer are very hot so it doesn't seem to be related to the tankless water heater. I've tried running the water in the farthest faucet until it's hot before turning on the washer - same result, barely warm water.
Any thoughts or suggestions before I call an appliance repair person?
