Common Dishwasher Problems in Tallahassee, FL
Dishwasher problems often show up as standing water, leaks, poor cleaning, dishes that stay wet, failure to fill, failure to start, unusual noises, or error codes. The symptom helps narrow the issue, but it usually does not identify the failed component by itself.
Seeing an error code? Use the Appliance Error Code Lookup for supported manufacturer-documented codes. If you need the exact model first, use the Appliance Model Number Finder.

1. Dishwasher Will Not Drain
A dishwasher that finishes with standing water can have a clogged filter, blocked drain hose, drain-pump problem, check-valve issue, garbage-disposal connection problem, or control fault.
- Check whether the filter is visibly clogged and clean it according to the manufacturer’s instructions.
- Look for a kink in the visible drain hose.
- If a garbage disposal was recently installed, confirm the dishwasher drain connection was prepared correctly.
- Note whether the dishwasher makes a humming sound when it should be draining.
- Write down any error code.
If dirty water repeatedly remains in the tub after basic checks, request diagnosis rather than repeatedly running another cycle.
2. Dishwasher Is Leaking
Dishwasher leaks can come from the door gasket, inlet hose, drain hose, pump, inlet valve, tub, spray system, or installation connections. Where the water appears can help narrow the source.
- Water at the front: may involve the door seal, oversudsing, door alignment, or spray pattern.
- Water underneath: can come from pumps, hoses, valves, seals, or internal connections.
- Water near a cabinet connection: can point to supply or drain plumbing rather than the dishwasher itself.
Stop using the dishwasher if the leak is large, worsening, or could damage flooring, cabinetry, or nearby electrical components.
3. Dishwasher Will Not Fill With Water
If the dishwasher starts but little or no water enters, possible causes include a closed water-supply valve, kinked supply line, inlet-valve problem, float or float-switch issue, door-latch problem, or control fault.
- Confirm the household water-supply valve serving the dishwasher is open.
- Check whether the dishwasher door closes and latches fully.
- Look for a visible object preventing the float from moving freely, if your model has an accessible float.
- Write down any error code.
4. Dishwasher Is Not Cleaning Dishes Well
Poor cleaning can come from clogged spray-arm holes, a dirty filter, low water flow, a circulation-pump issue, detergent problems, incorrect loading, low water temperature, or a cycle that does not match the load.
- Clean the filter according to the owner’s manual.
- Check whether spray-arm openings are visibly blocked.
- Avoid loading dishes so tightly that the spray arms cannot rotate.
- Use dishwasher detergent intended for automatic dishwashers.
- Confirm the selected cycle is appropriate for the soil level.
If cleaning remains poor after maintenance and loading checks, the dishwasher may need diagnosis of the circulation, heating, water-supply, or control systems.
5. Dishwasher Is Not Drying Dishes
Drying problems can involve the heating element, vent, fan, sensor, rinse-aid system, controls, or cycle selection. Some dishwashers use condensation drying rather than an exposed heating element, so drying behavior varies by model.
- Check whether rinse aid is being used if the manufacturer recommends it.
- Use the normal or heated-dry option when appropriate.
- Allow plastic items extra drying time because they retain less heat than glass or ceramic.
- Note whether the dishes are cold and wet or hot and wet at the end of the cycle.
6. Dishwasher Will Not Start
A dishwasher that will not start can have a power-supply, breaker, door-latch, control-lock, control-board, switch, wiring, or internal safety issue.
- Check the breaker.
- Make sure the door is fully latched.
- Look for a control-lock or child-lock indicator.
- Try canceling and restarting the selected cycle according to the owner’s manual.
- Write down any error code.
Do not bypass door-latch or electrical safety systems to force the dishwasher to run.
7. Dishwasher Stops Mid-Cycle
A dishwasher that starts normally and then stops can have a door-latch issue, power interruption, water-supply problem, overheating component, drain problem, control fault, or sensor problem.
Note when the dishwasher stops—during filling, washing, draining, or drying. That timing can help narrow the fault.
8. Dishwasher Makes Unusual Noises
Some dishwasher sounds are normal, including water movement, draining, and pump operation. New grinding, rattling, buzzing, squealing, or knocking can indicate debris, spray-arm interference, pump problems, bearings, or another moving component.
- Rattling: can come from dishes touching each other or the spray arms.
- Grinding: may involve debris or a pump-related component.
- Buzzing or humming: can occur during normal operation, but a new persistent sound paired with poor performance deserves inspection.
- Knocking: can happen when a spray arm strikes a tall utensil or dish.
9. Dishwasher Leaves Food or Grit on Dishes
Food residue can result from a clogged filter, weak circulation, blocked spray arms, incorrect loading, detergent issues, insufficient water, or a problem with the wash pump.
If the same dishes remain dirty in the same rack area, check whether a spray arm is blocked or unable to rotate freely.
10. Dishwasher Smells Bad
Odors can come from food debris in the filter, standing water, a drain problem, residue around seals, or the plumbing connection. Cleaning the filter and checking for trapped food is a safe first step.
If the odor resembles sewage or returns quickly after cleaning, the drain or plumbing connection may deserve attention as well as the appliance.
11. Dishwasher Shows an Error Code
Error codes vary by brand and model. They can point to drainage, filling, heating, leakage detection, door-latch, pump, sensor, or control problems. Write the code down exactly as shown before resetting the dishwasher.
Include the brand, model number, and code in your repair request. See the appliance brands page for more on brand and model identification.
Safe Checks Before Requesting Dishwasher Repair
- Confirm the dishwasher has power.
- Check the breaker.
- Make sure the door closes and latches fully.
- Clean the user-accessible filter according to the owner’s manual.
- Check whether the visible drain hose is kinked.
- Make sure spray arms can rotate freely.
- Check for a control-lock setting.
- Write down any error code.
- Note whether the problem occurs during fill, wash, drain, or dry.
- Stop using the dishwasher if there is a significant leak or electrical concern.
Avoid removing electrical panels, bypassing door switches, or disassembling pumps, wiring, or internal components unless you are qualified to do so.
When to Request Dishwasher Repair
Request service when the dishwasher repeatedly fails to drain or fill, leaks continue, cleaning or drying remains poor after maintenance checks, the appliance stops mid-cycle, unusual noises return, or an error code keeps coming back.

Repair or Replace the Dishwasher?
The symptom alone should not determine whether the dishwasher is replaced. A no-drain or leaking problem can result from both comparatively simple issues and more expensive pump, motor, tub, or control failures.
Age, repair history, failed component, parts availability, overall condition, and the actual estimate all matter. See our full guide to dishwasher repair cost in Tallahassee and whether the dishwasher is worth repairing.
Dishwasher Problem FAQs
Why is my dishwasher not draining?
Possible causes include a clogged filter, blocked drain hose, drain-pump problem, check valve, disposal connection, or control fault. The exact cause depends on the model and symptom pattern.
Why is my dishwasher leaking from the bottom?
Leaks underneath can come from pumps, hoses, valves, seals, the tub, or internal connections. If the source is not visible externally, diagnosis may require service.
Why are my dishes still dirty after a full cycle?
A dirty filter, blocked spray arms, weak circulation, poor loading, low water flow, detergent issues, or a pump problem can all reduce cleaning performance.
Why are my dishes still wet?
Drying depends on the dishwasher design, rinse aid, selected cycle, heating system, venting, sensors, and the materials being washed. Persistent poor drying may require diagnosis if settings and rinse-aid use are correct.
Should I keep using a dishwasher that leaks?
Do not keep running the machine if the leak is substantial, worsening, or could damage cabinets, flooring, or electrical components.
