Fault: "Operating Temp." What should I do?

There is a leak. The most common cause is a leaky Q1 valve, which would cause cooling water to flow into the vessel during the heating stage.

To test:

Turn the instrument completely off but keep the water supply on. Check to see if water is running out of the drain line. Water should not be running out of the drain line if the instrument is off. If it is, then you need to inspect and clean valves Q1, Q2, and Q3 (Q1 is the most important). To inspect the valves, turn off the water supply and refer to XT15 Service Procedure Drain Manifold Replacement (X5S005).

After inspecting the valves, turn your water supply back on and verify that no water is running through the drain line while the instrument is off. Run an extraction. If the vessel is not heating, contact ANKOM.
