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

Hey @Od1n & @Dean02 ! Official Samsung parts can only be provided during an engineer's repair. Please note that DIY repair advice cannot be posted on the Community, as it is against the terms of service. A post on this can be found here: https://eu.community.samsung.com/t5/news-rules-faqs/community-policy-on-dangerous-diy-unorthodox-rep...

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.

Perhaps Samsung should create products that can be fixed by their customers. This would be a sustainable way forward. Especially since you talk about how you want to be a sustainable company for the environment. 

An ideal way for you to move forward is have your product designers and engineers to design the products so that they can be fixed or repaired easily by the customers. This would put you head and shoulders above your competitors. 

If you cannot do this because your budget constraints get in the way of your profits, perhaps you can create a separate forum that allows your customers to ask questions and get help from your engineers.

Would be a terrible idea - the majority of DIY'ers have simply not the capability of carrying out repairs on their appliances and would be incompetent .

Could put them and others (say if they repaired it dangerously , forgot to put an earth lead back or something causing electrocution, or something that could cause a fire) . 

for this reason as well if i were in charge of things in a country I would ban all used/secondhand electrical Items being sold unless they had at least a PAT electrical test or paperwork stating if they have had repairs in the past and which competent technical engineer repaired the item .

Hey Andy, 

Firstly, many people are not as incompetent as you may think. People work on their own cars and sell them off, the other week a qualified mechanic didn't tighten the lug nuts on my friends wheels (my friend was able to turn them by hand). 

Secondly, people will try and fix things with or without professional help, so therefore it is wiser to have a place where people can come and get quality answers to help them avoid dangerous mistakes.

Lastly, this takes me back to designing the appliances to allow for easy customer repair, this goes hand in hand with modular and enhanced modular design. For example, you can have parts that are click and play, if one of these parts becomes faulty, you replace it with another part by simply clicking out the old part and clicking in the new part. 

With this ability the customer could upgrade their machine when a new part comes out that can improve functionality, they can also fix their own machine safely. You can find similar systems built for children to explain electronics (LittleBits). Imagine the electronic waste you could save.

A primary issue of our and pollution and climate crisis is the fact that we no longer have products that are fixable, when something breaks they need to be entirely replaced rather than replacing a small part. If you have a deeper dive into the problem then you will be able to find out more about this. 

If you have any more questions or would like to discuss this further, feel free to reach out to me via email (bmcm1024@gmail.com).

Cheers, 

Ben

thanks for your reply Ben. I suppose vehicle repairs are a different ball game and they are not Electrical appliances and I thought we were talking of Electrical Appliance Manufacturers on a Electrical appliance forum so motor vehicles are a different kettle of fix and maybe belong on a motor vehicle forum . 

But no, as long as manufacturers continue to make spare parts for a certain amount of time from launch of product for their laundry devices available to proper appliance engineers to fit and at reasonable prices so it does not cost near as much as buying a brand new machine then that seems OK to me - even there could be some kind of recondition part programme where parts are removed from scrapped machines and refurbished (if they need to be) and supplied that's another good Idea I think
