Frigidaire Dishwasher i10 — What It Means & How to Fix It
Water isn't reaching the tub fast enough — the under-sink valve, a kinked line, or a stuck float explain most i10 errors before any part needs replacing.
What this code means
i10 is Frigidaire's low-fill code: the unit opened its fill valve and water didn't arrive at the expected rate. Frigidaire's own error guide frames it as a supply problem first — and indeed the shut-off valve, the line, and the simple mechanical float inside the tub account for the bulk of cases.
Frigidaire's i-codes read as a lowercase i plus digits on the display. If yours shows an 'iC0' or letter-heavy variant instead, that's a control-family code — different page of your manual, different problem.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Shut-off valve under the sink not fully open | Very common | Yes — no tools |
| Kinked or pinched supply line | Common | Yes — visual check |
| Overfill float stuck in the raised position | Occasional | Yes — free it |
| Failed water inlet valve | Less common | No — technician job |
What you can try yourself
- Open the under-sink valve fully — it's the first suspect after any plumbing work or a house move.
- Trace the visible supply line for kinks or crushing.
- Find the float inside the tub (a small dome at the floor, usually front) and lift-release it a few times to make sure it moves freely; a stuck-high float blocks filling outright.
- Run the kitchen tap to sanity-check household pressure.
- Cancel, restart a cycle, and listen for the fill in the first minute. No fill sound with all the above verified points at the inlet valve — a technician's part.
When to call a technician
- No water enters despite an open valve, healthy pressure, and a free float.
- A buzz from the unit at cycle start with no water arriving.
- i10 alternates with the i30 leak code — stop and get professional eyes on it.
Typical professional repair cost: Inlet valve replacement typically runs $100–$200 including labor.
Frequently asked questions
Does i10 mean the same as no water at all?
It covers both slow and absent filling — the control measures rate, not just presence. A half-closed valve produces the slow version; a failed inlet valve or stuck float produces the dry version. The checks are the same either way.
Why does my Frigidaire show i10 only on some cycles?
Longer or hotter cycles can demand fill volumes that expose a marginal supply, while quick cycles squeak by. Intermittent i10 usually means a restriction rather than a dead part — kinks and part-closed valves before electronics.
Can hard water cause i10 over time?
Scale gradually narrows the inlet valve and its screen, slowing fills year by year until the rate drops below what the control accepts. In hard-water areas, mention it to the technician — a valve clogged with scale is a known repeat customer.

- Frigidaire Dishwasher i60 The water isn't heating the way the cycle requires — the element, its relay, or the temperature sensor is at fault, and all of them are mains-voltage parts for a professional.
