TL;DR

✓ Start with symptom: not filling, not draining, leaking, or not heating/drying.
✓ Leak protection often stops the unit; check for water in base and visible leaks first.
✓ Drain errors are commonly filter/hose/air gap restrictions.
✓ Avoid electrical repairs unless qualified.

Symptoms / When you see this

✓ Dishwasher stops with a code.
✓ Won’t fill or drains immediately.
✓ Water remains in the tub.
✓ Leak protection activates.

Root causes (grouped)

✓ Supply/inlet issues.
✓ Drain path restrictions (filter, hose, air gap).
✓ Leak detection triggered by water in base pan.
✓ Heater/temperature sensing issues (model-specific).
✓ Control state issues after power interruption.

Step-by-step fixes (safe, prioritized)

✓ Turn off power before inspecting leaks.
✓ Confirm supply valve is open and inlet screen is clear.
✓ Clean accessible filters; check drain hose kinks.
✓ If leak protection triggered, dry visible water and identify source before restart.
✓ Power-cycle after addressing physical causes.

What NOT to do

✓ Do not run repeatedly when leaking.
✓ Do not open electrical compartments unless qualified.
✓ Do not bypass leak sensors or door switches.

If it persists (escalation checklist)

✓ Record code and model number.
✓ Document when leak happens (fill vs drain).
✓ Use manufacturer service guidance for heater/control faults.

FAQ

Can I reset a dishwasher error code?

Power-cycling can clear transient faults. If it returns, address physical causes first.

Is standing water always pump failure?

No. Filters, hose kinks, and clogs are common causes.

What if leak protection triggered?

Stop operation and identify/dry the water source. Repeated leaks require service.

Why does it not dry?

Drying depends on heat, rinse aid, and design; a heater error is only one cause.

Can power outage cause errors?

Yes. Control state can be inconsistent after interruptions; a controlled restart can help after safety checks.

When should I call service?

For repeated leaks, heater faults, or persistent errors after cleaning/basic checks.

Where is model number?

Often on the door edge or frame; check the label inside the door.

Are codes universal?

No. Similar codes can mean different things across brands.
