What AE / E1 / FE (722-prefix) Means
On 722-prefix Kenmore dishwashers, AE and E1 report a detected water leak — the published detail is that an abnormally high circulation pump speed caused by a low water level triggers it — while FE reports an overflow, with the drain pump running automatically while it stands.
Common Causes of AE / E1 / FE (722-prefix)
- A genuine leak dropping the tub water level
- A water inlet valve leaking through and overfilling
- A stuck relay leaving the inlet valve energised
🔧 One Safe Check You Can Try
Turn off the dishwasher water supply valve under the sink and look at the floor of the cabinet beneath the machine for standing water before deciding anything.
⚠ Why You Shouldn't Go Further Than That
- Water escaping under a built-in dishwasher reaches flooring, cabinet bases and nearby sockets, so use should stop until the source is found.
- Leaving a leak alarm running while the machine keeps filling simply moves more water under the floor.
- Pulling a built-in dishwasher out without disconnecting water and power first is how a small leak becomes a large one.
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.
