Proper Water Cooler Use & Maintenance

The complete experts' guide — practices that keep your water cooler in top condition for over 10 years.

 20 Years of Experience  Service  Filters  Guides

A water cooler can run flawlessly for years — or give you trouble from the very first month. The difference is not the brand: it is how you use it. In 20 years of experience with water coolers in homes and large businesses, we have seen that almost every problem is prevented with a few correct habits.

Proper use in 5 points

If you read only one thing, let it be this.

1

Daily draw-off

Run water from every tap each day — no stagnant water.

2

Controlled hot water

Switch the hot tank on only when you need it — never permanently.

3

Bottle in the shade

Away from sunlight, consume within 2-4 days.

4

Correct installation

By a technician — the single most critical step.

5

6-month service

Regular check-up with filter replacement.

The 5 most common mistakes

These we see again and again during service calls.

 Bottle with high mineral content

Causes scale build-up, leaks and a noticeably poor taste.

 Stagnant water

The #1 cause of bad odour when you do not draw water from all taps.

 Hot tap left permanently on

Builds up scale and over time burns out the heating element.

 Sunlight on the bottle

Algae (green growth) develops inside the water.

 Neglected maintenance

Small issues turn into expensive breakdowns.

Correct daily use

Four habits that make the biggest difference.

  • Daily draw-off of 2-3 glasses from each tap (cold, hot, ambient).
  • Weekly boil cycle: if you do not use the hot water often, every Monday switch the hot tap on until the first boil, then switch it off.
  • Bottle consumption: 2-3 days in summer, 3-4 days in winter.
  • After inactivity: let 1 litre run from each tap before drinking.

Bottled or mains-fed?

Each type has its own critical variable.

BOTTLED COOLERS

Key: the water quality

Choose bottled water with low mineral content and a stable composition. Consume within 2-4 days of opening.

See bottled water coolers
MAINS-FED COOLERS

Key: the right filtration

Hard water or water with rust needs the appropriate filter, with professional service every 6 months.

Filter replacement: when

The most critical maintenance point on a mains-fed cooler.

The rule: every 6 months. Bring it forward to 3-5 months if the water quality is poor, consumption is high, or the hot tank runs continuously. Replace the filter earlier if you notice a change in taste, an odour, dark particles or white deposits in the water.

Water-mains works in your area? After such works are completed, the load of "bad" water is very high and filters clog up immediately. Schedule a filter replacement right afterwards.

 Cleaning & disinfection

For DIY cleaning, a natural solution of baking soda and vinegar is safe and effective, leaving no chemical residue. On the taps and the bottle valve avoid chemicals — use hot water only. The drip tray grille can even go in the dishwasher. For the internal tanks, professional disinfection is recommended every 6 months together with the regular service and filter replacement.

 Before & after holidays

If you will be away for more than a week: switch off the back switches and unplug it, empty and remove the bottle (or shut the supply on a mains-fed unit), and drain all the water from the taps and the rear drain plug. On your return, let 1 litre run from each tap before drinking. After 2-3 weeks of inactivity, a good flush is usually enough — a new filter is generally not required.

 SOS: installation determines everything

If you pay attention to one thing only, let it be this. A single mistake on day one can destroy a brand-new cooler.

  • Always transport upright — if it has been laid on its side, wait 24 hours before operating it.
  • Installation by a technician — the initial connection is the most critical step.
Water first, power second: First run water from all the taps, and only then connect it to the power. If done the other way round, the boiler runs empty and the heating element burns out.

Frequently asked questions

The most common questions from our customers.

Within 2-3 days in summer and 3-4 days in winter. Bottled water is a perishable product and after that there is a risk of microorganism growth.
Usually from stagnant water in the tanks, an old saturated filter, or an environment with strong odours that are absorbed by the water.
Yes, safely, with baking soda and vinegar — effective and leaving no chemical residue. Avoid chemicals on the taps and the bottle valve. Professional disinfection is recommended every 6 months.
If the cooler has not been serviced for over 1.5 years AND the compressor has burnt out, the cost of repair plus service approaches the price of a new one — then replacement is more economical. With proper maintenance, a cooler lasts over 10 years.
The cooler must be transported upright (otherwise wait 24 hours) and during connection water must run from all taps first and only then be plugged in — otherwise the boiler runs empty and the heating element burns out.
First and most important step: immediately shut off the water supply and unplug the cooler, then empty the taps. After that, contact us at +30 2106000621. The cause may be the float valve, water pressure or a connection — diagnosing and fixing it requires technical knowledge, so do not attempt to disassemble it yourself. Our team guides you safely, even with video support.
On a new cooler, a slight smell in the first few days is common and fades if you regularly draw water from all taps. If the smell persists or is strong, the tank needs a proper cleaning — a procedure that must be done in a controlled way. Contact us at +30 2106000621 and we will guide you step by step, safely. Avoid putting chemicals into the tank yourself without instructions.
