Step-by-Step DIY Fix Guide
- SAFETY: Disconnect power before inspecting.
- Check the drain hose routing — it must form a high loop secured under the counter at least 20 inches above the floor, or connect to an air gap fitting.
- Inspect the check valve (a small rubber flap inside the drain pump outlet) — it should open under flow and close freely when flow stops. Replace if it appears stuck open or deformed.
- Clean the drain filter.
- Restore power and run a rinse cycle, then check for standing water in the tub after the cycle ends.
If it's still not draining
- If the drain path looks clear but the code returns, the issue is more likely in the pump path or another less accessible restriction.
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- C5 persists after correcting hose routing and cleaning the filter
What This Error Means
Error C5 on your GE Appliances dishwasher means: The drain cycle completed in less time than expected, suggesting the pump ran but water did not fully drain — possibly due to a partial obstruction or the drain hose being too short or improperly routed. The dishwasher's self-diagnostic system detected this condition and paused the current cycle.
The most frequent cause is drain hose too short or not elevated with a proper high loop — water siphons back between drain events. Work through the causes and fix steps below in order — most GE dishwasher errors can be resolved without a service call.
Many cases of C5 can be resolved by the homeowner. The steps below cover the full DIY checks — if they do not resolve the error, a technician is needed.
The drain filter is the first thing to check on any GE dishwasher drainage error. It sits in the tub floor beneath the lower spray arm and traps food debris on every cycle. Cleaning it takes 5 minutes and resolves the majority of drainage faults without any further work.
Most Likely Cause by Symptom
The GE Appliances dishwasher may stop, pause, or refuse to complete the cycle normally.
Likely cause: Drain hose too short or not elevated with a proper high loop — water siphons back between drain events
Check first: SAFETY: Disconnect power before inspecting.
Water may remain inside the appliance instead of clearing normally.
Likely cause: Drain check valve stuck open, allowing water to re-enter the tub after draining
Check first: Check the drain hose routing — it must form a high loop secured under the counter at least 20 inches above the floor, or connect to an air gap fitting.
Performance may drop because airflow, filtering, or draining is restricted.
Likely cause: Partial clog in the drain filter reducing resistance — pump clears faster than expected but water returns
Check first: Inspect the check valve (a small rubber flap inside the drain pump outlet) — it should open under flow and close freely when flow stops. Replace if it appears stuck open or deformed.
Common Causes
- Drain hose too short or not elevated with a proper high loop — water siphons back between drain events
- Drain check valve stuck open, allowing water to re-enter the tub after draining
- Partial clog in the drain filter reducing resistance — pump clears faster than expected but water returns
- Control board misreading drain completion timing
What Not to Do
- Do not run the dishwasher if water is continuously siphoning back into the tub — standing water harbors bacteria and will re-contaminate clean dishes

How to Prevent It Recurring
- Verify drain hose routing during installation — a proper high loop is required to prevent back-siphoning
