Do you leave your steam cleaning machine in a van or storage shed after working in cold weather? If water left inside freezes overnight, it can damage internal components.
The short answer: in winter, drain all water from the boiler, water tank and feed line after finishing all the work, and store the machine somewhere warm. This article walks you through the 4-step freeze-prevention procedure outlined in the OPTIMA STEAMER user manual.

Why Is a Frozen Steam Cleaning Machine a Problem?
When water inside the machine freezes, pipes and other components can crack, leading to malfunctions and damage. In a steam cleaning machine, water flows from the water tank through the feed line into the boiler. If water remains in these components after use, it can freeze.
In What Order Should You Drain and Store the Machine?
1.Drain the boiler: Lower the steam pressure to about 2 bar (29 psi) or less, then slowly open the drain valve and let all the water out. Leave the drain valve open until the next use.
2.Drain the water tank: On diesel models, remove the drain plug at the bottom of the tank. On electric models, disconnect the connecting tube at the bottom of the tank to drain the water.
3.Drain the feed line and feed pump: With the drain valve open, disconnect the tube between the feed pump and the water filter, then blow out any remaining water with compressed air.
4.Store the machine: Keep the machine indoors or in a warm place to prevent freezing.
Follow proper safety precautions when draining the boiler. Steam is extremely hot, so wear appropriate hand and eye protection. Before draining, secure the steam hose and power cable, and watch out for slippery wet floors.
How to Drain Water Tank: Diesel vs Electric Models?
On the diesel models(OPTIMA XD/OPTIMA XDm), remove the drain plug at the bottom of the water tank.
On the electric models(OPTIMA XE/OPTIMA XEm), disconnect the tube from the bottom fitting to drain the water.
What If the Machine Has Already Frozen?
If you suspect the machine has frozen, do not operate it. Let it thaw slowly in a warm indoor space, then check it for damage first. If you notice any signs of damage, contact your dealer or the manufacturer and have it serviced before using it again.
Winter freeze prevention comes down to two things: leave no water inside the machine, and store it somewhere warm. Make these 4 steps part of your end-of-day routine to help prevent costly freeze damage to internal components.
