Having water run after door dispenser is released, caused hilarious but flooding situations. Sooo, I replaced the dispenser switch. Oddly the problem got worse. After a few days of using our hands to repeatedly press the dispenser lever which would work eventually, I was set to call for advice. But when I changed out the filter, suddenly the water flow stopped. ?? Then I could gear and see water spraying out of the back of unit... I found a leak in the line from the valve to the dispenser, cut it and out it back into valve. No more leak...and door switch worked? Must be related to low water pressure from leak. Good to know to check for leaks before replacing switch!
