I was curious about the water cooling cycle in that I'd never seen a temperature higher than 30C on my display. I asked the Degritter Team about this and I'm posting their reply since it might be of interest, in general. "Thank you for the email and welcome to the Degritter club! The Degritter has an integrated automatic cooling system. There are two temperature sensors in the machine - one directly in the cleaning tank and one near the filter block (which doubles as a cooler). When the temperature measured on these thermistors reaches ~35 C, then the machine starts the cooling process. This is necessary to avoid any damage to the record (warping starts around ~45 C). When viewing the temperature(s) after the wash, then yes, they will already be lower than during the cleaning since the cooling system is working throughout the cycle once triggered. The record drying process cools the machine quite a bit, for example. Heating in the machine happens because some energy generated by the 300W ultrasonic amplifier is converted to heat as heat loss. To some extent a warm(ish) water is better, since it helps with the cleaning (the average industry/laboratory cleaner usually has a heater in it and cleans at 70-80 C). In summary, your machine is working as should. Happy new year and happy cleaning!"
