What you are actually seeing
- A mild tingle from the machine or the sink
- Lights dimming when the machine runs
- The breaker trips as soon as the cycle starts
- Not this fault: A GFCI that trips with several appliances running
Ranked causes on a Conservator dishwasher
- Wash or drain pump motor winding failed — Ranked here because: this platform is mechanical by design, so wear parts and couplings fail as parts rather than as symptoms of a board
- Loose or corroded connection at the outlet or the terminal block — Ranked here because: these machines are commonly installed by the owner or the delivering dealer, and levelling and venting errors are the most frequent finding
- GFCI itself failing — Ranked here because: a supply fault imitates a component fault exactly and costs nothing to eliminate
- Water reaching a connection or the wiring — Ranked here because: the gasket is the cheapest thing on the machine to get wrong and the easiest to confirm
- Circuit overloaded or shared with counter outlets — Ranked here because: these machines are commonly installed by the owner or the delivering dealer, and levelling and venting errors are the most frequent finding
- Heating element failed to earth — Ranked here because: the heating circuit is a discrete, testable part of the machine with a clear pass or fail
What to check, and in what order
- Note what else is on the same circuit and whether the trip only happens with those running
- Test the GFCI with its own test button and check whether it trips with other appliances
- Switch the machine off at the breaker and leave it off while you work
- Note exactly when the trip happens: at start, at fill, at the heat step, or at drain
Steps you can safely do yourself
- Switch the machine off at the breaker and leave it off while you work — Tools: none — Estimated time: a couple of minutes
- Note exactly when the trip happens: at start, at fill, at the heat step, or at drain — Tools: none — Estimated time: one full cycle, watched
- Check the base pan and under the machine for water with a paper towel — Tools: paper towel, flashlight — Estimated time: about ten minutes
- Feel the outlet and the plug for heat and look for discolouration — Tools: none — Estimated time: a few minutes
- Note what else is on the same circuit and whether the trip only happens with those running — Tools: none — Estimated time: about ten minutes
