TLDR
On your AM16 DISHWASHERS unit, error 017 indicates that the wash tank water level is critically low, preventing operation. This usually points to a problem with the water supply, fill valve, or the wash tank pressure sensor. Begin by verifying the external water supply and inspecting the machine's fill system for blockages.
Technical Details
Repair Steps:
- Verify External Water Supply: Ensure that the water supply faucet to the dishwasher is fully open and that there is adequate water pressure. Check for any kinks in the supply hose or a clogged inline filter at the machine’s inlet.
- Inspect Water Inlet Valve: Locate the water inlet solenoid valve. Check if it’s receiving proper voltage when the machine attempts to fill. If voltage is present but no water flows, the valve may be stuck closed or faulty. A faulty valve can prevent the wash tank from reaching its minimum level.
- Examine Wash Tank and Filters: Power off and drain the machine. Inspect the wash tank interior for any large debris that could be obstructing the fill sensor port or the drain. Thoroughly clean the machine’s filters (strainers) to ensure proper water flow and prevent false level readings.
- Check Wash Tank Pressure Sensor and Tubing: The pressure sensor is typically located near the bottom of the wash tank or connected via an air trap tube. Disconnect and inspect the tubing for any blockages, kinks, or disconnections. The sensor itself might be faulty; test its continuity or resistance as per service manual specifications, if safely possible.
- Electrical Connections and Wiring: With power disconnected, check all electrical connections to the water inlet valve and the wash tank pressure sensor. Look for loose wires, corrosion, or signs of damage. A poor connection can mimic a component failure.
- Contact Hobart Service: If after performing these checks the error persists, the issue may require specialized diagnostic tools or replacement of critical components like the main control board, the wash tank pressure sensor, or the water inlet valve. Contact Hobart Service for professional assistance.
Common Questions:
Q: Why is my HOBART AM16 not filling with water for the wash cycle?
A: A common reason for the AM16 not filling is an issue with the external water supply (faucet closed, low pressure), a malfunctioning water inlet solenoid valve, or an obstructed wash tank pressure sensor that falsely indicates a low water level.
Q: What components are involved in regulating the wash tank water level on an AM16?
A: The primary components are the external water supply, the water inlet solenoid valve (which controls water flow into the tank), and the wash tank pressure sensor (which monitors the water level) along with the main control board which processes these signals.
Q: Is it safe to try and bypass the wash tank pressure sensor to run the dishwasher?
A: Absolutely not. Bypassing safety sensors like the wash tank pressure sensor is extremely dangerous and can lead to severe equipment damage, flooding, or electrical hazards. Always diagnose and repair the root cause of the error.
