What C5 Means
C5 means the unit isn't draining properly during the drain phase, distinct from C2's long-drain timing — C5 flags that drainage is incomplete or restricted rather than just slow.
Common Causes of C5
- Clogged drain filter or screen
- Blocked drain hose or air gap
- Failing drain pump
🔧 One Safe Check You Can Try
Check the drain filter/screen at the bottom of the tub for food debris, since a clogged filter is a common, owner-serviceable cause.
⚠ Why You Shouldn't Go Further Than That
- If the filter is clean and the hose is clear, the drain pump needs technician diagnosis.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
