Need some help with a dryer problem

Frogeye

We got a bosch condensing dryer about 10 weeks ago for a new build. It being a new build it has good airtightness and insulation, hence the condensing dryer to avoid butting a hole in the wall.

Its been getting very hot to touch on the outside after its been on for a short time. Plus its not drying the clothes. They just get hot and steamy. It doesn’t burn you to otuch but its not far off it. Its air intake is clear, the fuzz is removed from the filter, the water emptied and the Heat exchanger is clean. There is nothing else in the manual.

Called bosch and they sent an “ engineer” out. He came , reviewed the situation , called his tech support and the outcome is that our utility room is too warm, the air the dryer is taking in is too warm and it causing the dryer to overheat. The room is only at 23-24 deg C.

Has anybody else come across this problem? We can’t use a standard dryer with a vent and have no garage etc to put it. Is it even possible to get a dryer that will deal with this “ high temperature”.


Thanks

run it near an opened window and see if it behaves normally, if not get the engineer back, if you need an extension lead to run it uncoil it while the machine is on test, if it works normally then the engineer is correct, the machine is recirculating hot damp air, you will then have to secure a fresh air flow to the room

Have a look in the manual and see if there is anything about the operating temperature for the unit.

I would get on to Bosch's technical support department and ask them what type of dryer they think would be suitable for this environment. Bosch are a leading global brand in the area and should be able to sort this out. They sell dryers in a lot of countries warmer than Ireland.

It does sound to me like it isn't condensing properly.

You could move the machine outdoors and see if it operates correctly in the open air (on a dry day, obviously).

Manual was my first port of call. There is nothing in the manual on the air temperature. I did point that out and I mentioned that bosch supply hotter countries put it didn't seem register with the engineer. He told me to go back to the shop where I bought it and discuss with them.


I'm still awaiting their report.

thanks for the replies

Does manual mention ‘ambient temperature’?

If this is the best they can come up with, then certainly, tell the retailer to come and pick it up and get you a machine whose manufacturer will stand over it.

Turkey is a warmer country than Germany, perhaps Beko is the brand for you!?

re ambient temp you must remember that because the dryer is in a room where the op states is virtually airtight the dryer when drying is sucking in air from outside with a fan forcing it through a 2kw element absorbing moisture from the clothes and onto the condenser. after many decades as a white goods engineer I have yet to find a manufacturer who has developed a tumble dryer condenser that can absorb All the moisture as it passes through and in effect what happens in an almost airtight room is that the outside becomes as hot as the inside of the drum with hot moist air which is what the op initially described, bottom line is you need air circulation for any tumble dryer

Well then the issue is ventilation, not the temperature of the room.

Exactly, my suggestion to anyone in this type situation would be fit a bathroom type ceiling fan and vent it to the exterior

If the window is open it should work fine though, right?

Kind of defeats the purpose of having a condenser dryer if you have to let the heat out of the room.
