What C2 means (monogram dishwasher c2 error)
A monogram dishwasher c2 error on a Monogram dishwasher means the total pump-out time exceeded its limit — across the cycle the dishwasher spent more than about seven minutes trying to drain. Like C1 it points to a drain restriction, but C2 reflects a cumulative problem over the whole wash rather than a single slow drain.
Symptoms to look for
The signs below help confirm you are dealing with this condition rather than a different fault on your Monogram Dishwasher. You may see one of them or several together, and they can build up gradually or appear suddenly after a power event, a long door opening, or recent service.
- The display shows “C2”
- The dishwasher repeatedly tries to drain
- Each drain is slow and water lingers
- The cycle runs long or will not finish
Common causes
Several different faults can produce these symptoms. Working through the most likely causes in order helps separate a quick, owner-level fix from a problem that needs trained service and the correct Monogram parts.
- Partial drain restriction — flow is slowed throughout the cycle
- Blocked air gap — the air gap is partly clogged
- Dirty filter and sump — debris slows every drain
- Weak drain pump — the pump cannot keep up
Troubleshooting steps you can try
Work through these checks in order before calling for service. Stop wherever you are unsure, or where high-voltage parts, gas, the sealed refrigeration system, or the self-clean lock are involved, and hand the rest to a qualified technician.
- Clean the dishwasher filter and sump thoroughly.
- Clear the air gap and check the drain hose for partial blockage.
- Confirm the disposer connection, if used, is open and clear.
- If draining stays slow after cleaning, book service for the pump.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the drain pump, drain hose, air gap, and filter/sump. The correct part for your Monogram Dishwasher is matched from the model and serial number, and genuine Monogram components are fitted rather than generic substitutes so that performance, safety, and the appliance’s long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.
When to call a technician
A C2 that stays after cleaning the filter, air gap, and hose needs a technician to test the drain pump. When the fix calls for trained service, book a visit through our scheduling page and an experienced technician will diagnose and repair it.

Prevention and care
Regular care keeps this condition from returning on your Monogram Dishwasher. Keep vents, filters, and the condenser or ventilation path clean, avoid overloading or blocking airflow, check that doors and seals close cleanly, and follow the Monogram maintenance guidance for your model. Because this unit relies on electronic control, protect it with a stable, correctly rated power supply and have any built-in installation done to Monogram specification so the control never sees an out-of-range condition. If a code appears, note exactly what was shown before you reset the appliance — that record helps the technician reach an accurate diagnosis and avoid replacing parts unnecessarily.
