Nespresso error code 1003 indicates “Heat Not Complete”. That means you now have to make coffee without hot water. Because of thermos-block or, insufficient time, the machine does not get to prepare hot water.

This error code has been seen rather often in Nespresso Coffee Machines.

My friend Michel bought a Nespresso CitiZ Machine last year and he also faced the same problem as well.

I just bought this Citiz espresso machine, and after making a cup of coffee, I tried to follow the routine of making three long coffees and then two hot glasses of water. It worked till the hot water system falls and I received the error number #1003 thermos-block timeout. It can still brew coffee but not hot water.
Recently, I received this message from my friend Michel.

Following my recommendation, he contacted the Nespresso service center.

Kinel’s Observation

The Nespresso error code 1003 indicates that the heating process has not been completed. That signifies thermos-block timeout. Without hot water, coffee can still be brewed.

If your system displays the error code 1003, turn it off for a few moments before turning it back on. If the problem code continues to appear, contact Nespresso customer care.
