What F8E5 Means
JennAir's F8E5 page names a fill valve stuck open, and its instructions are unusually emphatic: turn off the water to the dishwasher if you can, press Cancel once to silence the alarm tone, shut the door, and do not turn off the power. If you cannot reach the water supply, then turn off the power instead.
Common Causes of F8E5
- A fill valve mechanically stuck in the open position
- Debris in the valve seat holding it off its seal
- A valve that has failed electrically in the energized state
🔧 One Safe Check You Can Try
Shut the water supply off at the dishwasher's valve before anything else, then press Cancel once to silence the tone and close the door. JennAir specifically says to leave the power on and the door shut, because the machine keeps pumping out while the valve is passing.
⚠ Why You Shouldn't Go Further Than That
- This is the one dishwasher code where the manufacturer's own instructions tell you not to cut the power, because the drain pump is what is keeping the water off your floor.
- Opening the door while the valve is passing water defeats the containment JennAir is describing, which is why the page says to shut it.
- A valve stuck open will not fix itself, and every hour it runs is water through the machine, so this is a same-day call rather than one to leave.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
