Error codeF3E2
ApplianceDishwasher
Seeing F3E2 on a Maytag dishwasher means the thermistor or OWI sensor went through calibration and did not pass. That is a separate statement from a sensor that is open or shorted; here the sensor is not described as broken in either of those ways, only as having failed the calibration step.
Neighbouring sensor and heater entries
F3E1 covers the thermistor or OWI being open or shorted, which is the other condition in the same manual list.
F3 E2 is how the support page words the sensor fault: thermistor or OWI sensor, with a 30-second power reset as its troubleshooting step (breaker off at the home panel on a hard-wired unit, then back on).
F4E2 belongs to the heater: open, unplugged, or a failed relay.
What an owner can and cannot do
The technical manual gives no homeowner routine for F3E2. Cut power to the machine before any panel is opened, and treat anything involving the sensor as work for a technician.
Maytag dishwasher service in San Francisco and the Bay Area

Model compatibility: Maytag reuses codes across series and model years, so F3E2 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
The thermistor or OWI sensor failed its calibration.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
