Degraded o-rings on middle-drawer spray arm supply tube cause leaks
Owner of a SHP65T56UC/01 reports the beige o-rings at the middle-drawer spray arm connection are badly degraded; a repair tech confirms they are not sold separately and the spray arm supply tube (11018097) is the replacement.
What to check. If you see leaks at the back of the middle drawer, the o-rings cannot be bought alone; budget for the spray arm supply tube (11018097).
Dishwasher stops randomly with no error code - door switch or control board
A repair blog documents a SHP65T56UC that stops mid-cycle with no error code; the cause is the door switch or control board, and parts were under $100 versus a $350 shop quote.
What to check. If the unit stops randomly with no code, suspect the door switch/control board; it is a DIY-able ~$100 parts fix.
E-18 / E-08 low-water-level errors persist after inlet valve and drain filter replacement
The owner replaced the water inlet valve and drain filter and the constant beeping with E-18/E-08 codes continued, so the low-water-fill diagnosis is not a simple valve swap.
What to check. A constant-beep/E-18 unit may not be fixed by replacing the inlet valve; check actual water fill level and the inlet/outlet plastic assembly before spending.
Spray arm plug into water source wears out and is difficult to engage
An owner repair story on PartSelect reports the spray arm plug into the water source wore out and became hard to engage, requiring spray arm replacement.
What to check. A worn spray arm plug is a straightforward, low-cost replacement that resolves engagement/leak issues at the drawer connection.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
