Low water level detected during operation; display shows E10 and cycle may abort.

Safety first: Turn off power and allow the tank to cool before reaching into the machine.

Step-by-step checks:

• Inspect water level: With the machine filled, verify that the water level matches the CMA fill line or specification. If low, check for leaks or an open drain.
• Clean float assembly: Locate the tank float. Remove any scale, food debris, or grease that may prevent free movement. Ensure the float guide is clean.
• Test float switch: With power OFF, disconnect the float switch and test continuity while manually raising and lowering the float. Replace the switch if it does not change state reliably.
• Check for leaks: Inspect the tank, pump seals, and drain fittings for visible leaks that could lower water level during operation.

When to call a technician: Persistent low-level faults after cleaning and switch replacement may indicate structural leaks or plumbing issues that require professional diagnosis.
