Optima Steamer Powerful Steam Cleaner

What is a steam cleaner?

A steam cleaner, oftentimes called a vapor steam cleaner, is a cleaning appliance that uses steam. A vapor steam cleaner allows the user to quickly clean, sanitize, and dry surfaces simultaneously

How does optima steamer work?

The Optima Steamer was one of the first commercial-grade mobile steam cleaners to enter the market. It was introduced in 2004 by SJE Corporation for commercial and industrial applications. It serves as an alternative for applications where pressure washers would be too destructive. Before the Optima Steamer was released, mobile steamers used a coil system. This system created wet steam that was very similar to that of a pressure washer. 


The engineers behind Optima Steamers created a more advanced system, the single potboiler system. This combines the coil system's ability to heat up rapidly with a pressured pot-boiler system to produce vapor. The boiler is constructed of three layers to endure high temperatures and maximize combustion efficiency. Heat in the form of exhaust gasses is transferred down and up in the combustion chamber and is eventually released through the exhaust resulting in a pure vapor jet of steam. This process, reverse burning, increases combustion efficiency by 30%.


The Optima Steamer advanced boiler system allows the user to clean and sanitize simultaneously while never having to worry about pressure drops or changes in temperature.

Types of Steam - Wet Steam vs. Dry Steam vs. Superheated

The Optima Steam Cleaner uses superheated steam and has a moisture control feature so the user can choose between wet or dry steam. Wet steam is water vapor that produces water droplets while dry steam is just water vapor. 

Wet Steam

Wet steam (condensed or unsaturated steam) is both a liquid and gas. It is formed by heating water in a flow-through coil to 212˚F (boiling point) producing a mixture of steam and water. Wet steam consists of more than 5% water which creates water droplets and is commonly used in the removal of grease, oil, residues, and other unsanitary build-ups. Wet steam uses more water consumption to produce more volume at the outlet to move debris off surfaces and away from the area. 


Tip: Water causes corrosion. When using wet steam avoid cleaning fragile equipment such as turbine blades, low-pressure steam piping, and heat exchanges. 

Dry Steam

Dry steam (or saturated steam) is a gaseous phase that is formed by heating water in a closed chamber to 212˚F (boiling point). Dry steam doesn’t contain any water droplets and is commonly used for barrel cleaning, food prep cleaning and sanitizing, control panels and conveyor line cleaning and sanitizing, auto detailing, removing bacteria, mold, yeast, and fungi. If dry steam is heated past the boiling point it becomes superheated steam.

Superheated Steam

Superheated steam is a gaseous phase, heating water at a very high temperature (above boiling temperature) and does not contain water droplets. Superheated steam is commonly used for steam engines, pest control, drying, cleaning, steam oxidation, curing, energy systems, etc.

Optima Steamer Troubleshooting

Common troubleshooting problems you can fix on the job. Can’t troubleshoot the problems, no worries! Bring your machine to our shop or contact us to schedule a service call and well get your machine working in no time.

No Lights & Alarm Sound But Power & Steam Switches Are On

This could be due to the power plug not being connected properly or a blown fuse. Check your electrical power source and power plug to make sure it’s not disconnected. Check to make sure the emergency stop switch isn’t pressed. If the machine lights are still off and there is no alarm sound, check the fuse to see if it needs to be replaced.

Refill Water Tank Icon is Red and Flashing 

If the float switch is not detecting water in the water tank, this could be a result of water shortage or the float switch in the tank is defective. Check the water level of the tank and add water. If the problem persists, disconnect the wire from the float switch to see if the signal clears. If the error disappears replace connect wires and replace the float switch.

Refill Fuel Tank Icon is Red and Flashing

The fuel tank is low and needs to be filled or there is a malfunction with the float switch in the water tank. Disconnect the wire from the float switch to see if the signal clears. If the error disappears replace connect wires and replace the float switch.

Boiler Level Error Icon is Red and Flashing

This means the boiler water level is low. Check the water filter and replace it if dirty. Check the water pump and water probe sensors, clean, and replace if necessary.

Pressure Switch Error Icon is Red and Flashing

Defrost the machine and/or replace the 8.5 bar pressure switch. If the water probe sensors are the cause, clean or replace all the water probe sensors of the boiler.

Water Pump Overrun Error Icon is Red and Flashing

Experiencing the water pump running over time due to water filter blockage, malfunction of the water pump, or the water probe sensors. At initial operation, the water pump has a run time limit of three minutes for the XD model and five minutes for the XE Model. The water pump is programmed to run up to 60 seconds once the low water probe sensor detects water. 

Check the water filter, if it is dirty replace it. Check the water pump and water probe sensors, clean or replace if needed.

Thermistor Error Icon is Red and Flashing


The thermistor detects the low temperature (under 32˚F). Cold weather can trigger low-temperature detection. Defrost the machine and try again, if the problem persists, replace the thermistor.

Display Error Code

DT32 or ET32

This means the thermistor has been shorted and needs to be replaced.
DT33 or ET33

This means the thermistor has detected high temperatures, over 392˚F. This could be a result of the pressure switch or thermistor malfunctioning and needs replaced. Replace the 8.5 bar pressure switch. 

Flame Detecting Error Icon is Red and Flashing

Flame Detection Fault 

Check and clean components of the combustion chamber and check the blower fan. Check the fuel filter or fuel pump for any signs of malfunction and replace if needed. The flame detector and pressure switch (8.5 bar pressure switch) could be malfunctioning and needs to be replaced.

Abnormal Detection of Flame Detector

The flame sensor has been exposed to light from outside. Check the rubber packing on the flame detector and replace it if needed. 

Boiler Pressure Above 9 bar (130 PSI)

Malfunction of the pressure switch or water probe sensors can cause this. Replace the pressure switches, clean or replace the water probe sensors of the boiler if needed. 

Using distilled water can also cause this. Use normal tap water (above 15 ppm).

Machine Is Leaking Water or Steam

During the cold months, it's likely due to the Y-strainer cracking or the piping line. Thaw the machine, inspect it for any other damage and replace the Y-strainer and other parts if necessary. 

In other cases, the safety valve broke due to overpressure. If the safety valve opened below 8 bar, replace the valve. If the safety valve opened over 8 bar, then contact your distributor. 

Water Supplying Tube of Water Pump is Hot

Replace the non-return valves and damaged parts.

Water Tank is Abnormally Hot

Clean or replace the air purge valve. If the problem persists, replace the thermistor.

Static Electricity on the Spray Gun or Machine

This results from the machine not being grounded properly. Use the grounding chain located at the rear bottom of the machine.
