We have a Buderus 600 boiler, which is approximately 10 years old. It has a code 2 showing on it and it is not working. We have had plumbers out who have replaced the pump, thermostat, timer switch and still no luck. Any ideas?

A code 2 is a circulation problem. Ensure all valves are open and the pump is running
