Frigidaire FFCD2418US Dishwasher Problems & Error Codes — Overview
The Frigidaire FFCD2418US is a 24-inch built-in dishwasher that shares the same control platform and drain system with other Frigidaire models in this series. The most frequent service calls involve drain faults (i20 code), power interruption errors (PF code), and door latch issues (CL or Cd code). The i20 drain fault is by far the most common problem and is usually installation-related or caused by clogged filters rather than a failed pump.
Most problems on this model can be fixed without replacing electronic parts. The drain system is straightforward but sensitive to installation errors like leaving the disposer knockout plug in place or routing the drain hose below the required 32-inch height. Power faults clear themselves once household voltage stabilizes. The heat delay code (HO or Hd) appears when the water temperature or heating cycle is delayed, but the owner guide does not break down specific heater component failures for this exact model number.
Most Common Problems on This Model
- i20 drain error code displayed Disposer knockout plug was not removed during installation, drain hose is pinched or blocked, drain hose is routed below 32 inches from the floor, or the filters and sump are clogged with food debris.
- PF power failure code displayed A voltage drop of 10% or more or a momentary power interruption triggers this code, and the fix is to verify stable incoming power and then press Cancel or turn off power for five minutes to reset.
- CL or Cd door latch code displayed The door is not fully closed or latched, so check that the door closes squarely and the latch engages, or replace the door latch mechanism if it will not latch even when the door is pushed firmly.
- HO or Hd heat delay code displayed The dishwasher is indicating a delayed heating condition, which may be related to incoming water temperature or the heater circuit, but the manufacturer guide does not specify exact component checks for this model.
- Dishwasher will not drain or drains slowly The drain hose is kinked, the filters and sump are packed with food soil, or the disposer knockout plug is still in place blocking the drain path.
- Door will not stay closed or latch The door latch striker or latch assembly is worn or misaligned, or the door hinge is bent preventing the door from closing squarely into the latch.
- Dishwasher loses power or resets mid-cycle Household voltage dips below the threshold or the breaker supplying the dishwasher is loose or undersized, triggering a PF code and stopping the cycle.
- Code will not clear after troubleshooting Unplug the dishwasher or turn off the breaker for at least three minutes to clear i20, or five minutes to clear PF, then restore power and press Cancel before starting a new cycle.
Parts That Commonly Fail
| Part | Notes |
|---|---|
| Drain hose | Amazon | Check for pinch, blockage, or incorrect installation height before replacing. |
| Door latch assembly | Amazon | Fails when the door will not latch even after confirming the door closes squarely. |
| Filters and sump (glass trap area) | Amazon | Clean regularly to prevent i20 drain faults, not a replaceable part under most conditions. |
| Control board | Amazon | Only suspect if codes persist after all other causes (drain, power, door) are confirmed good. |

When to Call a Pro
Call a technician if the i20 code will not clear after you have confirmed the disposer knockout is removed, the drain hose is routed at least 32 inches high and is not kinked, and the filters and sump are clean. Also call for service if the door will not latch after verifying the door closes squarely, if the HO or Hd code persists and you need heater circuit diagnostics, or if the PF code returns repeatedly even when household voltage is stable. Any work involving the control board or internal wiring should be done by a qualified appliance technician.
