# Monogram microwave 18 code — the Power Watch indicator

### What the appliance is actually doing

The Power Watch indicator, not an error. It reports that the appliance has seen a supply problem, and it is cleared rather than repaired.

### Which machines this one applies to

Monogram built-in microwaves and microwave drawers. Monogram says plainly on their own range and oven table that they cannot list every code for every model past and present, so a code missing from their table is not proof that your appliance cannot raise it — and a code in it is not proof that yours can. The model number settles it.

### What to do about it

- Clear it at the panel.
- If it comes back regularly, the supply to the appliance is what to look at rather than the appliance.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 614-3572](tel:+13056143572) and describe what the display is doing before booking anything.
