Perry E Richmond , VA November 05, 2024 Appliance: General Electric Dishwasher GDT655SSJ4SS Ge Dishwasher Gdt655ssj4ss: Ge dishwasher (6 years old). How to replace Part Core Refund. Dishwasher started random beeps when not running about a year ago. Beeps got more frequent, sometimes 3 times an hour. Diagnostics showed nothing wrong. Display then went dark. Used YouTube to diagnose and found led on constant on main control board, but with still 14VDC output on pins 1 & 5 to UI board. Ordered UI board on Thursday, had it on Friday! (Live in Virginia). Followed Youtube to replace UI board, about an hour to do. Works perfectly and no more beeps! Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
