When is a problem with dishwasher urgent?
Treat a dishwasher problem as urgent when it creates an immediate safety exposure, active damage, loss of an essential service in dangerous weather, or rapid worsening.
What this means
Dishwasher covers drainage, filling, cleaning, leaking, and power. Relevant observations include Will not drain, Will not fill with water, Leaks during a cycle, Dishes remain dirty, Has no power. The correct response depends on age, design, climate, usage, installation, recent work, and the exact manufacturer instructions; these observations narrow next steps but do not prove a failed part.
Safe checks

- Move people away and use only a normal safe shutoff or disconnect when accessible.
- Call emergency services for immediate danger; otherwise contact the relevant qualified trade.
Stop and get help if
