How to fix dishwasher error codes?

 
Common Dishwasher Error Codes Explained Clearly (Bosch, Whirlpool, Samsung)
 

Dishwasher error codes can be frustrating, but they help identify specific problems that need attention. Bosch, Whirlpool, and Samsung dishwashers each have distinct codes indicating different issues — understanding these codes and their meanings can help you quickly troubleshoot and, possibly, resolve dishwasher concerns without needing extensive repairs.

 
How to Identify Error Codes
 

Dishwasher error codes usually appear as alphanumeric codes displayed on the appliance's front panel. Typically, these include a combination of letters and numbers, such as "E24," "F2," or "OE." Your dishwasher's user manual includes a complete list that corresponds directly to your unit.

If you have misplaced your manual, you can typically find model-specific information online or on the manufacturer's official website.

Here are some common error codes and solutions based on brands:

 
Bosch Dishwasher Common Error Codes and Solutions
 

E15 Error – Water Leakage Detected:

• Check for pooling water at the dishwasher base. Remove the dishwasher from beneath the counter carefully and verify if leaks are visible at hose connections or pan.
• If leaks are evident, replace damaged hoses or seals.
• If no visible leaks appear, reset the dishwasher by tilting it back slightly to drain excess water collected in the base.

E24 Error – Dishwasher Not Draining Properly:

• Inspect and clean the dishwasher's filter located at the bottom—clogs or debris often cause this code.
• Ensure that the drain hose has no kinks or blockages; reposition and reconnect as necessary.
• If cleaning filters and hoses don't resolve the issue, the drain pump may need inspection or replacement by a professional.

E22 Error – Filter or Pump Blocked:

• Remove dishwasher baskets and access filter area at the base. Clean thoroughly, removing any foreign objects or food debris.
• Check drain pump impeller and clean if needed to guarantee clear water drainage pathways.

 
Whirlpool Dishwasher Common Error Codes and Solutions
 

F2/E2 Error – Drainage Issue:

• Check drain hose for twists, blockages, or improper installation—ensure that water freely exits through hose.
• Clean out pump components and filters located at the dishwasher base.
• If unit still doesn't drain correctly, your pump motor might require professional servicing or replacement.

F6/E4 Error – Float Switch or Water Level Problem:

• Inspect float assembly (usually located near dishwasher base inside the tub). If stuck, gently clean and reposition it correctly.
• Ensure water inlet valves are functioning properly—replace defective valves as necessary.

F1/E1 Error – Heating Issue:

• Check heating element visually for damage or corrosion inside dishwasher tub. Replace if visibly faulty.
• If element looks intact, verify connections and continuity with a multimeter or have it checked by a service technician.

 
Samsung Dishwasher Common Error Codes and Solutions
 

OE/OC Error – Overfill Water Issue:

• Inspect float sensor inside dishwasher—clean the float assembly from any debris causing inaccurate water level sensing.
• Ensure drain hose isn't blocked or kinked. Water must drain properly for accurate water sensing.

LE Error – Leak Detected:

• Inspect door seals and gaskets carefully for visible damage or misaligned components. Replace broken or worn seals.
• If there are no visible issues with seals, check all internal hoses for leakage signs and replace damaged components accordingly.

HE Error – Heating Element or Temperature Sensor Issue:

• Check heating element visually and verify functionality with test equipment (e.g., multimeter).
• Inspect temperature sensor(s) for proper connection and continuity—replace defective sensors if identified.

 
When to Contact Professionals (Bosch, Whirlpool, Samsung)
 

Routine maintenance and cleaning can typically solve common dishwasher error codes effectively. However, replacing electrical components, water pumps, or sensors often requires specialized tools and knowledge. For complex problems or persistent errors, getting in touch with a professional dishwasher technician is advisable.

For example, if you're in St. Louis or around the Nashville area, local appliance repair specialists like Hoffmann Brothers can deliver trusted services promptly, helping bring your dishwasher back to proper working condition safely and reliably.

 
Prevent Dishwasher Error Codes with Regular Maintenance
 

Regular dishwasher maintenance helps avoid frequent error codes and costly repairs. Keep your dishwasher clean (especially filters and spray arms), use recommended detergents, and ensure drain hoses remain clear. Simple preventive measures performed periodically will prolong dishwasher efficiency and service life.
