GE Front Load washer overflowing detergent tray on rinse cycle

[ChipM]

Hi everyone,

Thanks in advance for your help on this one.  GE GFW850SPN2RS front load washer is leaking from the front left corner after the rinse cycle.  An appliance tech came out and said he had another customer with an identical problem, but he hasn't solved it - his guess was the dispenser-to-drum hose was leaking and he replaced a hose clamp.

When removing the tray, water is all over the front edge of the dispenser funnel area and clearly running over the front edge of it.  I removed, disassembled, and cleaned the dispenser tray.  The siphon cups all work as expected when filled with water.  Water pressure to the machine is 40PSI.  Removed front cover and door assembly and checked plumbing from dispenser tray to drum, checked drum/door seal, and none of that appears to be leaking.

I would appreciate any advice on where to go next with this one - I assume the dispenser is overfilling and allowing water to run over the edge and down the inside front of the machine, but I don't know why it would do that except for a dirty tray or high water pressure.

Thanks!
