When your JennAir Dishwasher displays the F2-E2 code, it means the appliance's self-diagnostic system has detected a fault that requires attention. A single power cycle that clears the code is not a reliable fix if the underlying cause has not been addressed.

Call (800) 555-0190JennAir dishwashers with the TriFecta wash system rely on three spray arm levels for full coverage. Clogged spray arm jets, a failing wash pump, low water temperature (should be 120°F at the inlet), or hard water mineral buildup are the most common causes. We inspect and clean all spray arms and verify water pressure on every service call.
Standing water after a cycle typically means a clogged mesh filter (clean monthly), a blocked drain hose at the garbage disposal or air gap connection, or a failed drain pump. Check the fine filter at the bottom of the tub first — JennAir recommends cleaning it monthly.
JennAir dishwashers use F-code errors to indicate specific faults. F5-E1 means the door won't lock, F8-E1 indicates a water supply issue, F6-E4 points to a flow sensor problem. Our technicians can read the full error history from the control board for accurate diagnosis.
Leaks from the door are usually caused by a worn door gasket, a warped door, or a clogged spray arm directing water at the door seal. Leaks underneath typically come from a loose hose clamp, a cracked sump, or a failing pump seal. Do not continue running a leaking dishwasher — water damage to cabinetry and flooring can be significant.
