question edited for clarity.
Air conditioning will often dim the power a bit as the compressor draws a lot of power. It may be that your Start Capacitor has failed and this is why you are noticing it, plus the fact you don't hear the compressor running. The water doesn't drip because there is no frost and no condensate. You need a refrigeration guy. It is quick to diagnose and they keep start capacitors in the van. Call out plus 30 minutes.
Sad...
The bulbs called for (60W) do get VERY hot...
(but the owners manual I found indicate a 60W
USA style lamp... (appeared to be a E16 (Edison)).
Euro lamps have higher voltage
(and FRANKLY speaking) better heat tolerance...
If you are terribly in love with this unit.. I would first
suggest calling the "SUPPORT" to see if their
"ENGINEERING" already has a solution...
ELSE you should be looking for a couple CERAMIC
(like glazed porcelain) sockets and prepare to
FIELD ENGINEER a proper/safe remedy...
My best suggestion...
Call support
Dimplex Obsidian OBS20 User Manual Page 9
Then contact your favorite hardware... (or LAMPS +)
and ASK the MOST COMMON clear candelabra bulb socket
That sports a CERAMIC type socket... E12 or E14 ...
When I was "converting" a Spanish chandelier..
I used GLAZED Porcelain "EDISON twelves" (E12).

Hope this helps

Finally, Please don't type in all CAPS, it is considered SHOUTING and is harder to read.
Repair Clinic has some good ideas, but your model is discontinued
Here are the steps you might want to follow:
Setting the Draining Cycle Times (Dump Interval): This setting controls how often the unit dumps the water. You can adjust this setting to reduce the frequency of water dumping.
Setting the Drain off Delay Time (Dump Delay): This setting controls the delay time before the unit starts to dump the water after it has been turned off.
If adjusting these settings doesn't work, there could be other issues with your unit. For example, a continuous water dumping problem could be due to a faulty dump valve or a problem with the float valve.
Why do you need to dismantle this? Some of these types of cooler do not have replaceable parts inside. They are usually classed as a "Throw away" machine. It is often easier and cheaper to replace it than repair it.
