Heat pump dryer not drying and no water in tank

[Dean02]

Hi guys, I have an issue where the cycle goes on for hours, the clothes are still damp and no water has been collected in the tank. All filters are clean, have even stripped machine down and cleaned heat exchange and condenser like brand new but still has the same issue. Does anyone know what else the problem could be?

Hey mate, so I do have the exact same issue with my DV80M52103W/LV dryer. Bought it back in 2018, served me very well until now. I have been reading comments from other people and the issues they have been having with this unit, so I knew my time would come. So it stopped condensing therefore no water to drain, and it stopped producing heat. I spend so many hours googling and watching videos on YouTube about how the heat pumps work and what problems they have and how to tear them apart and how to fix the problems. I took it down once, and cleaned it thoroughly, but I didn't open the compartment where the condenser is cause i didn't have the time or space to properly do it. After assembling, still no luck. Almost everyone online, regardless of the brand, they state that if you clean the condenser properly it should be fine. I haven't found not a single one stating on YouTube that there could be a refrigerant leak, apart from some comments on some forums from people that have contacted Samsung. Should I trust what Samsung said? I don't know yet, however, I found a DIY instruction manual how to change the refrigerant and it's not worth it. I am planning to disassemble it once again down to the condenser compartment, clean it thoroughly and give it a try. If not, then I will check the motherboard cause I found a store selling PCBs for this dryer, and if they sell it there must be a reason. not that expensive around 60£ + shipping. will get back to you soon.

Hi mate, thanks for taking the time to respond, it’s nice to know I’m not alone trying to figure out what’s going on with these dryers as all the engineers want to do is tell you you need a complete new heat exchange circulating system , which I’m not entirely convinced of myself. I can’t see much that can go wrong with them except as you say with a leak of the gasses which is highly unlikely. 
As I said earlier, I completely stopped the machine down (with a little help from YouTube) and the heat exchanger and condenser looked like new when I put it back together again but still not working. I think the problem lies elsewhere, maybe a sensor or the pcb as you say. Please let me know how you get on with the new pcb and if that solves your problem. It’s ridiculous that nobody out there seems to know how to fix this problem. 
Kind regards 

Dean

My dryer that was bought in 2018 has packed up AGAIN. Paid £190 in 2021 as it was out of warranty. Not willing to pay that again. The moderator has said DIY repair advice shouldn't  be posted. Well the repair I had done was done by a "Samsung verified company". Why don't they just admit they made a rubbish dryer. Also won't be trusting Samsung again. I think the heat exchange is the problem.

Completely agree, what’s the point in the forum if you can’t give helpful advice to others with the same issues on a dryer that obviously has major problems.
