According to page 63 of the Munchkin Gas Fired Boiler manual I found at http://www.htproducts.com/literature/lp-185.pdf:

Fault Code F03 description:

"Interrupted or Shorted Return (Inlet) Thermister."

To fix/remedy the problem:

"1. Check the electrical connection to the thermister on the outlet manifold. Verify 5 VDC by checking in Molex connector. Verify thermister

values by referencing chart in this manual.

2. Replace thermister if necessary."

Hope this was helpful.
