SOURCE: pump in boiler (worcester 24I)keeps stopping

Electric motors are always equipped with a magnetic starter, composed of a magnetic contactor and an overload relay. It protects the motor from burning out when the current drawn exceeds the setting of the overload relay by cutting the power supply.
Furthermore, motors draw more current during starting and draws even more when the load driven is heavy.
Check the following for early prevention of burning out of the motor windings:

  1. Motor windings
  2. Motor temperature
  3. Line current
  4. Motor noise
  5. Load
The usual cause in the rise of motor temperature, line current and noise is the wearing out of the motor bearings. When the bearings wear out, the motor has difficulty in driving the load and draws more current and temperature rises or the motor rotor touches the stator and causes a grinding effect that produces the noise. When the motor always stops, replace the motor bearings and check continuity of the motor terminals with its body. There should be no continuity between the motor body and its terminals, otherwise rewinding is necessary. In your case check the pump impeller for any obstruction.
Note: Continuity test is done using an ohmmeter. With continuity means zero resistance. No continuity means infinite resistance. You may actually need the help of a qualified electrician.

Operating worcester bosch 240 gas boiler


Control systems operate on a much lower voltage than the boiler. You should be able to put any kind of thermostat in for it. Just be sure of the wiring when doing it. If its a line voltage stat, I'll need more information to advise correctly.

Lighting the pilot light on a Worcester 24CDi combi boiler.


Most of these boilers don"t have a permenant pilot light they have electronic ignition that lights the burner when you are calling for heat or hot water, is there enough water pressure in the boiler ( there is a small gauge on the bottom r/h side of the boiler the needle should be sitting at between 1 - 2 if not enough pressure the boiler won"t light )

My central heating system comprises a worcester bosch system boiler and honeywell smartfit controls. The problem I am having is that the central heating doesn't seem to knock off at the preset temperature...


You could possibly have an ignition problem. The controller will go into a lock-out condition if flame is not established. Turning the temperature control down and then back up may be serving to reset the control system so it tries again.
