What Does Monogram Dishwasher Error Code i30 Mean?
Error code i30 on a Monogram dishwasher means the flood protection system has been triggered. The anti-flood float switch in the base pan has detected standing water in the drip tray beneath the tub. The dishwasher stops filling and activates the drain pump continuously as a safety response.
Common Causes
- Internal water leak – A loose hose connection, cracked pump seal, or failed door gasket has allowed water to pool in the base.
- Overfilling – A stuck-open fill valve caused the tub to overflow into the base pan.
- Suds overflow – Incorrect detergent or excessive detergent produced foam that flowed into the base.
How to Troubleshoot
- Tilt the machine back – With power off, carefully lean the dishwasher back 45° to drain water from the base tray and reset the float switch. Hold for 30 seconds, then return to level.
- Inspect for the leak source – After draining the base, run a short cycle and look for drips under the door seal, at hose connections, or under the unit.
- Use correct detergent – Only use automatic dishwasher detergent — never hand dish soap or laundry detergent.
