I searched for air conditioner service photos on my laptop and found this gem instead. I thought I would share this with my readers because many of my regular customers use ice in drinks service, and some use ice to display the produce. But first, let’s talk about how people used ice-cooling hundreds of years before mechanical refrigeration was invented.

Historically, ice was the first media to maintain below ambient temperatures in cellars to preserve perishable goods. Ice was harvested by peasants and maybe slaves from the mountains and somehow transported to towns and castles, and seamen towed icebergs found in the northern hemisphere seas to the ports. Workers cut icebergs into suitable size blocks after towing them to the port. Entrepreneurs sold ice blocks to wealthy people, who alternately stored ice in the cellars, keeping the foods fresh for an extended period.

The filthiest ice maker I ever seen

A site manager of a popular venue in north London recently called me to sort out his ice maker. One of the owner’s issues was that the ice was poor quality. The second part of the job was to fit a water filter feel line and do general maintenance. Ice machine maintenance and water filter replacement are typical refrigeration engineers’ jobs. Nothing that day predicted I’m about to meet my worst ice maker so far. Indeed, I have seen many filthy ice makers during my career, but this one was the filthiest ice maker I have ever seen. I don’t know, and I cannot say for sure whether bar staff currently used this ice maker or not.

Besides lack of general cleaning, disinfecting and maintenance, there is a chance your ice maker is plumbed in incorrectly. Incorrect plumbing may cause phenomena known as faeces and urine in the ice bin. Yes, it is true. I’m not making this up to scaremonger ice maker users. The problem may occur when the toilet is flushed, or the dishwasher goes into the drainage cycle, and the wastewater is then pushed in every direction in the waste pipe. Should the ice maker drain be plumbed into the same sewage, the water rushing in the waste line may be pushed into the ice maker drain and straight into the ice maker bin.

To prevent problems with your ice maker, it has to:

  • be wiped down daily
  • weekly disinfection
  • descaling every two to three months, depending on the hardness of the water in your area.
  • clean the condenser every three-months
  • replace waterer filter three-months
  • besides the above routine, you need to follow manufacturers maintenance guidelines.

Should you need further assistance with your ice maker(s), please feel free to contact me any day of the week to discuss the service options I can offer you.
