TLDR
On your AM16 DISHWASHERS unit, error code 033 indicates that the fill valve has remained active longer than the system's maximum allowed fill time. This typically points to an insufficient water supply or a blocked fill path. Check the water supply, hose, and pressure to resolve this issue and restore normal operation.
Technical Details
Repair Steps:
- Verify Incoming Water Supply: Ensure that the main water supply valve to the dishwasher is fully open. Check for any upstream shut-off valves that might be partially closed or turned off, restricting water flow to the unit.
- Inspect Fill Hose for Kinks or Obstructions: Carefully examine the fill hose connecting the water supply to the dishwasher. Look for any visible kinks, bends, or external obstructions that could be impeding water flow. Straighten any kinks found.
- Check Water Pressure: Confirm that the incoming water pressure at the dishwasher connection point is within the specified range of 15-65 psi (1-4.5 bar). Use a pressure gauge if available. Low water pressure will cause the fill time to exceed the allowed limit, triggering this error.
- Manually Clear the Error: Press the ENTER button on the dishwasher’s control panel to attempt to clear the error. If the error immediately returns or the machine fails to fill, proceed with further diagnostics.
- Inspect the Fill Valve for Debris/Fault: Turn off the water supply and disconnect power to the dishwasher. Access the fill valve (solenoid valve). Inspect its inlet screen for any trapped debris, mineral deposits, or scale buildup that could be restricting water flow. Clean the screen if necessary.
- Check Electrical Connections to the Fill Valve: With power still disconnected, check the electrical connections to the fill valve solenoid. Ensure they are secure and free from corrosion. Use a multimeter to verify proper voltage supply to the valve when the machine calls for water (this step requires caution and electrical knowledge). Also, measure the resistance of the solenoid coil; an open or shorted coil indicates a faulty valve.
- Consider a Faulty Fill Valve: If all previous checks are clear and the error persists, the fill valve assembly itself may be faulty. It might not be opening fully, opening too slowly, or failing to seat properly. Replacement of the fill valve may be necessary. Always consult the specific Hobart AM16 service manual for detailed component testing and replacement procedures.
Common Questions:
Q: Why does my Hobart AM16 Dishwasher show error code 033?
A: Error 033 indicates that the dishwasher’s fill valve has been active for a period longer than the maximum allowed fill time, suggesting an issue with the water supply, flow rate, or the fill valve itself.
Q: What is the recommended water pressure for a Hobart AM16 Dishwasher?
A: The Hobart AM16 Dishwasher requires incoming water pressure between 15 and 65 psi (pounds per square inch) for optimal operation and to prevent fill-related errors.
Q: Can I fix the 033 error myself or do I need a technician?
A: You can often troubleshoot initial causes like a closed water supply, kinked hose, or low pressure. However, if the issue persists after these checks, or if it involves inspecting internal components like the fill valve or electrical connections, it’s best to contact a qualified Hobart service technician.
