Likely causes

- PossibleDelay timer accidentally setSome units have a start delay feature that looks like it isn't turning on.
- Less commonFailed control board or power switchNo response even after confirming power and an empty tank.
What to do
- Check the tank-full indicator; drain the internal tank per the manual even if it doesn't look completely full.
- Confirm the unit is plugged in firmly and the outlet has power by testing it with another device.
- Reset any tripped GFCI outlet and check the breaker panel.
- Look for a delay timer setting on the remote or panel that may be counting down before it starts.
- Unplug the unit for a full minute to reset it, then plug back in and try again.
- If it still won't power on with a confirmed outlet and empty tank, the issue is likely internal.
