TYPE A PLAIN WASHER

Diagnosing seepage can come down to one worn component—Type a Plain Washer (part 03-1407-07) is a common replacement item. Symptoms can present as seepage, intermittent operation, abnormal noise, or a cycle that won’t complete normally—depending on where this part sits in the system. After replacement, run at least one full cycle and recheck for leaks, vibration noise, and anything that loosens during operation. Stopping a persistent leak usually means replacing the sealing surface, not just tightening hardware. A short post-repair check—visual inspection plus a full cycle—helps confirm the issue is resolved without introducing new leaks or noise. A correct-fit replacement helps restore predictable operation and reduces repeat service calls. Take a photo before disassembly so you can confirm orientation and fastener locations during reassembly. Recheck fasteners after a short run-in period; vibration can loosen hardware if it isn’t seated correctly. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces. Clean the area around the repair so debris doesn’t interfere with fitment or sealing surfaces.

If the part interacts with water, do a leak check during the first run and again after a short operating period.
