Hobart dishwasher displays E14; chemical dosing system error (detergent or rinse aid).

Safety first: Wear appropriate chemical-resistant gloves and eye protection when handling detergents and rinse aids. Disconnect power before servicing pumps.

• Check chemical levels: Verify that detergent and rinse aid containers are not empty and that pickup tubes are fully submerged.
• Inspect pickup lines: Look for kinks, air leaks, or crystallized chemical blocking the tubing. Replace hardened or brittle tubing.
• Prime pumps: Many Hobart models require priming after changing containers. Use the manual prime function to draw chemical into the lines.
• Test pump operation: During a cycle, listen for the chemical pumps. If silent, check electrical connections. If they run but do not draw chemical, the pump head may be worn.
• Replace defective pump: If a pump motor is seized or the pump head is badly worn, replace the chemical dosing pump assembly with a Hobart-approved unit.
