Dishwasher A00194401, Replaces c8a400
This is the motor capacitor for compatible dishwashers. The capacitor provides the electrical boost needed to start the wash motor and supports smooth motor operation throughout the cycle. When the capacitor fails, the motor can’t generate enough torque to start — resulting in a dishwasher that hums loudly but won’t circulate water, or one that trips the breaker on startup. It’s one of the most overlooked components in a dishwasher diagnosis and one of the cheapest fixes before committing to a full pump or motor replacement.

Confirm the complete model number before ordering. Similar parts may use different connectors, dimensions, hose positions, electrical ratings, or mounting points.
- Dishwasher hums loudly during the wash cycle but no water circulates
- Motor struggles to start or takes multiple attempts to begin a cycle
- Breaker trips when the dishwasher tries to start the wash cycle
- Dishwasher runs intermittently — works sometimes, fails other times
- Wash cycle starts but motor cuts out shortly after
- No spray action despite the dishwasher filling with water normally
- Part Number: A00194401
- Part Type: Dishwasher Motor Start / Run Capacitor
- Construction: Aluminum housing, moisture and heat resistant, quick-connect terminals
- Buying Options: New OEM or Certified Pre-Owned (1 in stock)
- Vendor: XPart Supply Ltd. — Canadian stock, expert support
- Skill Level: Intermediate — electrical component, basic appliance repair experience recommended
- Always disconnect power to the dishwasher before beginning any repair
- Discharge the old capacitor before handling — capacitors can hold a charge even after power is disconnected
- Match the capacitor’s electrical ratings to your motor’s specifications before installing
- Use the quick-connect terminals for a secure, low-resistance connection
- Secure the capacitor in its mounting bracket to prevent vibration during cycles
- Run a full wash cycle after installation to confirm smooth motor startup and operation
A failed capacitor is the most common cause of a dishwasher that hums but won’t circulate water — and it costs a fraction of a full pump replacement. Before ordering a new circulation pump, test the capacitor with a multimeter set to capacitance mode. If the reading is significantly below the rated value (or reads zero), the capacitor is the problem. Replacing it first could save you $100–$200 and 45 minutes of pump disassembly.
