What Does Error iB0 Mean?

The Westinghouse Dishwasher error code iB0 suggests a potential issue with the drain pump, which may lead to unusual noises during operation. To address this, first, locate your dishwasher's model number and check the official user manual for any related error codes. If the iB0 code is not referenced, try performing a power reset by turning off the dishwasher at the power supply, waiting for 5-10 minutes, and then restoring power to clear any transient faults.

Possible Causes

  • Drain pump assembly failure
  • Electrical connection issue
  • Blocked drain hose

How to Fix Error iB0

DIY Fix Check documentation and basic reset

  1. Locate your dishwasher’s exact model number (e.g., printed on the inside door or rating plate).
  2. Search the official Westinghouse user manual for that model’s error code list to verify if iB0 is referenced — many manuals include a “Failure Codes” section.
  3. Perform a basic power reset by turning off the dishwasher at the power supply (either unplugging or switching it off at the breaker), waiting 5–10 minutes, then restoring power. This can clear transient faults in some units.
  4. Run a short cycle to see if the display clears. If it does not, continue to professional support.

Technician Only Consult official service manual and diagnostic tools

  1. Obtain the official service or technical manual specific to the exact Westinghouse dishwasher model; official manuals usually list all diagnostic codes and meanings.
  2. Connect diagnostic tools if available (brand-specific service interface), and check control board logs for iB0-specific fault entries.
  3. Perform any listed built-in diagnostics and follow error code troubleshooting steps documented by the manufacturer.
  4. If codes remain undocumented (like iB0), inspect common fault areas: control board communication lines, display panel ribbon, and sensor circuits for signs of damage or improper connection.

Parts needed: Control board/service interface, Display panel assembly, Sensor harnesses

🛑 When to Call a Pro:
  • If the error code cannot be decoded from the official manual after model identification.
  • If the dishwasher shows physical symptoms such as no water flow, heavy leaks, or electrical sparks in addition to the unknown error.
