What are the commonly replaced parts in a dishwasher?
For the Frigidaire FDSH450LAF2A dishwasher, the most commonly replaced parts are the ones tied to filling, draining, sealing, and starting: the water inlet valve, drain pump, door seal, and the control or user interface parts. These parts wear from normal use, clogs, and moisture exposure.
- Drain parts: standing water, slow drain, or a cycle that ends with water in the tub (often drain pump or drain hose)
- Fill parts: not filling, weak wash action, or long fill times (often inlet valve or water-level pressure switch)
- Sealing parts: leaks at the door edges (often door seal)
- Controls: won’t start, unresponsive buttons, or random stopping (often user interface or electronic control board)
- Detergent delivery: detergent left in the cup or cup not opening (often detergent dispenser)
These are examples of parts on this model’s parts list that commonly get replaced:
| Symptom | Likely part category | Example part on this model |
|---|---|---|
| Dishwasher won’t drain | Drain system | Crosley dishwasher drain pump A00044328 or crosley dishwasher drain hose 807032601 |
| Dishwasher won’t fill | Fill system | Dishwasher water inlet valve 807445905 |
| Leaks at the door | Door sealing | Crosley dishwasher door seal 117158011 |
| Buttons don’t respond | User controls | User interface,assembly ,w/board-touch 5304528982 |
| Detergent not dispensing | Dispenser | Dispenser,detergent A00130341 |
- Food soil and mineral buildup restrict water flow and drainage
- Heat and moisture stress electrical parts (control board, user interface)
- Door sealing surfaces compress and deform over time
- Hoses kink or develop internal buildup
We recommend these fast checks first because they solve many “bad part” symptoms:
- Clean the filter and remove trapped debris (see the owner's manual)
- Confirm the door fully closes and latches
- Verify the drain hose is not kinked and the disposer knockout plug is removed (if connected)
- Use fresh automatic dishwasher detergent and avoid blocking the dispenser
- Confirm home water pressure is in a normal range (the manual notes 20 to 120 psi) and incoming water is at least 120°F

Can I look up Frigidaire parts by model number?
Yes. We can look up replacement parts for your Frigidaire dishwasher by using the full model number FDSH450LAF2A; that pulls up the correct parts list and diagrams so you can match the exact component (like a drain pump, water inlet valve, or control board) to your dishwasher.
For FDSH450LAF2A, use the model number exactly as shown on the rating label and in your paperwork. Your owner's manual also includes a place to record the model and serial number, which helps you keep the right information handy.
- Enter the full model number: FDSH450LAF2A (include all letters and numbers).
- Use the model-specific parts list to narrow by system (controls, pumps, door parts).
- Compare the part name to your symptom (no drain, no fill, won’t start, leaking).
- Match connectors and mounting points before ordering.
- If multiple similar parts appear, confirm by diagram location and description.
These are examples of parts available for FDSH450LAF2A that often relate to common symptoms:
| Symptom | Part to check | Example part on this model |
|---|---|---|
| Won’t drain | Drain pump or drain hose | Crosley dishwasher drain pump A00044328, crosley dishwasher drain hose 807032601 |
| Not filling | Water inlet valve | Dishwasher water inlet valve 807445905 |
| Won’t start or dead controls | User interface or control board | User interface,assembly ,w/board-touch 5304528982, dishwasher electronic control board 117518761 |
| Leaks at the door | Door seal | Crosley dishwasher door seal 117158011 |
Dishwasher parts are highly model-specific. Using FDSH450LAF2A ensures you get compatible electrical components (like the user interface and electronic control board) and correct-fit mechanical parts (like the door seal and drain hose), which prevents returns and repeat repairs.

Can I replace dishwasher parts myself?
Yes, for the Frigidaire FDSH450LAF2A dishwasher, we can replace many common parts ourselves if the repair is straightforward and we can safely shut off power and water first. For electrical diagnostics or major disassembly, follow the safety guidance in the owner's manual and use a qualified technician.
These repairs are typically manageable with basic hand tools and careful reassembly:
- Cleaning and reseating the door seal area; replacing a worn seal such as the crosley dishwasher door seal 117158011
- Replacing a leaking or clogged drain hose like the crosley dishwasher drain hose 807032601
- Fixing “won’t drain” symptoms by checking the drain path and, if needed, replacing the crosley dishwasher drain pump A00044328
- Addressing filling issues by inspecting the supply line and, if needed, replacing the dishwasher water inlet valve 807445905
These involve higher shock risk, more troubleshooting, or more chances of miswiring:
- Control and touch panel issues (for example, the dishwasher electronic control board 117518761 or the user interface,assembly ,w/board-touch 5304528982)
- Water-level sensing and related fill problems (for example, the crosley dishwasher water-level pressure switch A00055408)
- Circulation and wash performance repairs that require pulling the unit and accessing the sump area (for example, the crosley dishwasher circulation pump A10281701 or the crosley dishwasher sump 5304520660)
The manual is clear that servicing requires power to be disconnected; we also shut off water to prevent leaks.
- Turn off electrical power at the breaker (do not rely on the control panel)
- Shut off the dishwasher water supply valve
- Protect the floor with towels and a shallow pan before disconnecting hoses
- Take photos of wire connections and hose routing before removal
- Run a short test cycle and check for leaks after reassembly
| Repair type | Typical difficulty | Common risk |
|---|---|---|
| Door seal, drain hose | Low | Leaks if not seated/clamped correctly |
| Drain pump, inlet valve | Medium | Leaks, pinched hoses, loose clamps |
| Control board, user interface | High | Shock risk, misdiagnosis, wiring errors |
Dishwashers combine electricity and water, so the safest DIY repairs are the ones with clear symptoms and simple access. When the issue points to controls, sensors, or repeated leaking after a repair, using the correct model-specific part and procedure prevents repeat failures and water damage.

What is the most common problem with a Frigidaire dishwasher?
On Frigidaire dishwashers like model FDSH450LAF2A, the most common problem is poor cleaning or water left in the tub, usually caused by clogged filters, a restricted drain path, or loading that blocks spray. Low-fill and leak conditions are also frequent and start with simple checks.
- Clean the filters and the sump area; clogs commonly cause weak wash and drain issues.
- Confirm the water supply shutoff is fully open.
- Inspect the drain hose for kinks or pinches.
- If connected to a disposer, make sure it is empty and the knockout plug is removed.
- Verify the door is fully closed and latched.
- Make sure the dishwasher is level (leveling affects leaks and draining).
| Symptom | Most likely cause | Next step |
|---|---|---|
| Dishes still dirty | Dirty filters or blocked spray path | Clean filters; reload so spray reaches dishes and the detergent cup |
| Water in bottom after cycle | Clogged filters or restricted drain | Clean filters and sump; check drain hose routing |
| Fills slowly | Shutoff not open or supply line pinched | Open shutoff fully; straighten supply line |
| Leaking/overflow | Loose inlet connection or not level | Check connections; level the unit |
| Code | What it points to | What to do |
|---|---|---|
| I10 | Low fill | Check shutoff valve and pinched supply line |
| I20 / I40 / IF0 | Drain restriction | Clean filters and sump; check for a blocked drain hose |
| I30 | Leak/overflow in bottom pan | Check inlet connections and leveling |
- Crosley dishwasher drain pump A00044328 (drain or pump-out problems)
- Crosley dishwasher drain hose 807032601 (kinks, restrictions)
- Crosley dishwasher door seal 117158011 (leaks at the door)
- Dishwasher water inlet valve 807445905 (fill problems)
Restricted draining and low fill reduce wash pressure, leaving soil behind and causing odors; leaks can also stop the cycle.
For model-specific loading, cycle selection, and troubleshooting steps, use the FDSH450LAF2A owner's manual.
