I have a frigidaire dishwasher that trips the breaker within 20 minutes of running. The circuit breaker is showing 120ish volts and the outlet seems fine based on my meter results. I have replaced the heating element, thermostat and thermistor. It will run fine when the heating element sensors are disconnected. I have also plugged it in to an extension cord and ran it fine on a 20amp circuit (it is on a dedicated 15amp circuit).
Anyone have any idea what might be going on here? Any troubleshoot ideas?
