ParticipantRe: Hotpoint Module Programming
If I remember correcctly, put card in device, switch macine off. insert device (with card) into socket of module and restore power to machine. Green light will flicker whilst download in progress. Steady green light indicates sucessful download, red light means down;load failed. The card is only a one-shot item, but if download fails, in my experience (been a few years since I did one), you can retry.

In your opinion, which you are absolutely entitled to and I would fight to defend your right to hold that opinion. What I was trying to highlight is that some words are very offensive to many people. Whatever their characteristic traits, would you equally use the terms “nigger”, “paki”, “spic”, “wog” “chinky” Et.c. Et.c. amongst people you did not know?

And a “PIKEY” is what, exactly? I am assuming you may be referring to the travelling community.

A single-pressure absorption refrigerator uses three substances: ammonia, hydrogen gas, and water. At standard atmospheric conditions, ammonia is a gas with a boiling point of -33°C. The system is pressurized to the point where the ammonia is liquid. The cycle is closed, with all hydrogen, water and ammonia collected and endlessly reused.The cooling cycle starts with liquefied ammonia entering the evaporator at room temperature. The evaporated ammonia is mixed with hydrogen. The partial pressure of the hydrogen is used to regulate the total pressure, which in turn regulates[clarification needed] the vapor pressure and thus the boiling point of the ammonia. As the ammonia boils in the evaporator, it pulls heat from the refrigerator’s interior and provides the cooling required.
The next three steps exist to separate the gaseous ammonia and the hydrogen:
1.In the absorber, the mixture of gases enters the bottom of an uphill series of tubes[why?], into which water is added at the top[how?]. The ammonia dissolves in the water, producing a mixture of liquid ammonia solution and hydrogen. The gaseous hydrogen collects at the top of the absorber, while the liquid ammonia solution flows to the bottom.
2.The next step separates the ammonia and water. In the generator, heat is applied to the solution to distill the ammonia from the water. Some water vapor and bubbles remain mixed with the ammonia. This water is dried out in the final separation step, by passing it through the separator, an uphill series of twisted pipes with minor obstacles to pop the bubbles, allowing the collected water to drain back to the generator.
3.Finally, the pure ammonia gas enters the condenser. In this heat exchanger, the hot ammonia gas is cooled to room temperature and hence condenses to a liquid[clarification needed], allowing the cycle to restart.

You’ll probably find the “cylindrical compressor” houses a heater and the fridge is the (very) old-fashioned absorbtion type, full of an ammonia based refrigerant. the pcb is more than likely a changeover device enabling the fridge to work off mains or 12v dc when connected to the auxilliary socket at the rear of the towing vehicle.

Yes and no – to keep it simple. The tank/general assembly is an old indesit design. If I’m right in my thinking it is made in China by Haier. I have seen loads Indesit/Hotpoint/Haier models where the spot wleds come adrift. Again if I remember correctly, the tank is N/A and non-repairable. We alwways used to BER them but I daresay you may be able to effect a repair using blind (pop) rivets.

ParticipantRe: LEC T2855W Fridge freezer freezing in fridge
The likeliest culprit is the diverter valve located adjacent to the compressor, mounted on the left hand upright of the cabinet (as viewed from the back). There is a pcb inside which is prone to melting. The best way to cure is replacement of the complete unit which is a systems job. I have known colleagues solder just the pcb in with success, but if the pcb shows no sign of burning whole unit will need to be replaced as it is possible for valve to stick. Personally I prefer to replace the whole unit.
