Manitowoc Ice E10

What does Manitowoc Ice E10 mean?

Code E10 is the evaporator-flooding fault for dual-TXV, dual-circuit/single-evaporator machines: during the first 6 minutes of the freeze cycle, the average compressor discharge-line temperature (T2) fell below the average of the six previous cycles.

Symptoms

• E10 logged on a dual-TXV machine
• Discharge line cooler than normal early in freeze
• Ice quality/production drift

Common causes

• Circuit-2 TXV overfeeding
• Overcharge after service
• Control ending harvest with liquid still in the evaporator

Diagnostic steps

1. 01

   Check the log pattern

   Repeated E10s across cycles confirm a real flooding trend on the second circuit.

2. 02

   Weigh the charge

   Verify the exact nameplate charge — overcharge is the simplest explanation and the easiest to rule out.

3. 03

   Analyze circuit 2

   Apply the dual-TXV operational analysis table to isolate the overfeeding valve.

4. 04

   Repair then verify

   After valve or charge correction, confirm discharge-line temperature behavior returns to the normal pattern.

When to call a professional

Refrigeration-circuit work on this machine (gauges, refrigerant recovery, TXV or compressor replacement) requires an EPA-certified refrigeration technician, and Indigo units built on R290 propane additionally require flammable-refrigerant service procedures. If the fault returns after the basic checks here, book a qualified ice-machine technician rather than continuing to reset the unit.
