John Lewis JLTDC01 – 91609605600

I have done the search on this dryer, but any info seems quite confusing. The dryer is working ok apart from there is very little heat. It does heat to a very low level after ten minutes or so, but the customer says it is nothing like it normally is. I have checked the usual, there are no blockages etc, filters are clear. Compressor and fan working. Pumps water to the holding tank etc. I must add that this is the first heat pump dryer I have been to, so I am not sure what I am looking at. I have been through the siting situation, and although it is in a garage, it has worked perfectly well there for five years. Yesterday when I went through the checks, the ambient was around 16 to 17 degrees, so should have worked perfectly, but for any fault. The only thing I can come up with is the possibility of a faulty NTC which is mounted on the side of the heat pump dryer. I get the feeling that there is very little wrong here, but I just can’t see it. Any help greatly appreciated. Cheers. Steve.

not seen one of these my self yet but from what i can see there is no heater. so the drum heat id derived from the compressor and recycling the heat from the condensor. according to the graphs in the manual looks like your max temp on a cotton dry seems to peak around 55 degrees amd that only if i am understanding the graph

not sure if you have it will send it to you

low on gas maybe?

The one I saw of these that was the same symptoms as yours I put down to the ‘heat pump’ side of things. Charged for my time in checking it over as nothing more I could do with it.

As stated they do naturally run at a very low temperature.

Dave, Yes that is the way it seems to work. There is a small lift out panel on the side of the evaporator, and the temperature is quite low. {e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} degress does seem to be a fair drying temperature, so I would guess that you are correct.
Mikehha, Low gas is a possibility, but unlikely, I think a blockage is more likely.
timdowning, Yes, I am in the same situation that you were. I will try the NTC, and after that I will have to assume a fault within the system.
Thanks for your help fellas. Steve.

I have been back with the aid of the supplied tech info, (many thanks to electrofix) and gone through the diagnostics checks. I keep getting fault code E32, with is described as “conductimetric sensing oscillation frequency too low” ?? This equates a fault in the moisture detection side. I have checked both brushes and both are ok, and I have tried a new NTC, but to no avail. I am now left with two possibilities. Either there is a fault within the gas system, or the main PCB is faulty. I am getting no heat on the timed side, so am dubious as to which of these possibilities is most likely? It’s a good job my customer, to whom I have been going for many years, is patient! Any more input greatly appreciated fellas. Cheers. Steve.
