Ventilate error -


The following procedure works when you get the ventilate error:



The Ventilate sign can be due to one or more of the following reasons:
Cause 1- Water leaking from the inlet valve below the water tank. The hose from the inlet valve to the pump can be air locked. When using the hand pump, do not thrust its nozzle too deep
Cause 2- Blockage in the passage of water due to clogged passage anywhere between the pump and espresso delivery nozzle.
Cause 3- Pump is not working. Open steam/water outlet knob and hear the pump work. If you do not hear any noise from the pump, this may be the main cause.
Cause 4- Flow meter is faulty. This part is like the water meter for homes. It measures the flow of water and signals the electronic board. The malfunctioning flow meter will not send signals even when water is flowing through it.
Cause 5- Hose is disconnected and water is not flowing in the system.
Cause 6- O-rings at hose connection is leaking, reducing the water flow to be sensed by flow meter.
Cause 7- Boiler gasket is leaking. Reduces flow of water through the system.
Cause 9- Brew unit is blocked, blocking flow of water through the flow meter. This also causes pump to slow down and ultimately stop with muffled sound within 15 seconds.
Cause 10- Brew unit not connecting brew valve, preventing flow of water. Same sign under cause 9.
Cause 11- Steam is leaking. Registers reduced flow of water at the flow meter.
Cause 12- Solenoid valve is blocked or solenoid coil is bad. Same observation as cause 9.
Cause 13- Electronic Control board is bad. Though rare it can happen due to condensed water from leaking steam. When steam is leaking or boiler is leaking, machine should not be used any more to prevent steam shorting the Electronic board.
Some of the above causes can be checked and corrected before seeking technical help. Do not assume anything without physically checking each of the following:
1- Make sure the water tank is full. If the water tank has water level float, make sure the float is in its housing and it floats as water is filled in the tank. If the level float does not rise with the level of water, then replace the float.
2- Water is not leaking from below the tank. The inlet valve is good. If leakage is present, replace the gasket in the water inlet valve.
3- Prime the machine by opening the hot water knob for 20 seconds or pressing the hot water button. Hot water flow shows the boiler is not blocked with minerals and pump is good. The solenoid valve is good.
4- Water & steam flowing normal, check the brew group for blockage. Determine when was the last time brew group was cleaned. Clean the brew group as explained elsewhere on these pages. If the machine has pre-ground function, try making a fake espresso (without coffee). Make regular espresso in other models to make sure that water goes through brew group and espresso is dispensed.
4- If hot water does not flow because the pump is not activated, then pump is bad. Replace pump.
5- Pump starts to work but within few seconds its sound is muffled and finally stop. This indicates there is serious blockage in the water line or the boiler is clogged with mineral deposits. If water is leaking and seen on the counter top, the chances are that water is leaking from hose connections(replace O-rings) or the boiler is leaking from seams (replace boiler).
6- Prime the machine by opening steam outlet for 20 seconds. Steam flow shows that steam boiler / steam outlet is not blocked. If the steam does not flow, then steam boiler or steam passage is blocked. Replace steam boiler or steam valve
7- Check the solenoid valves to make sure that they open & close as the coil is energized. Solenoid valve is located between the pump and boiler. The pump is activated simultaneously as the solenoid valve when espresso selection button is pressed. Some models may have a solenoid valve near the steam valve. In these models, the solenoid valve is activated to allow passage for steam/hot water. If the valve is not functioning, the ventilate sign will appear.
7- Hear the pump work when priming the machine. Louder noise from the pump can be due to
** air-locked water hose, or
** water is not sucked from the tank or the pump is sucking air instead of water or
** the diaphragm inside the pump has lost flexibility and not developing pressure to push water forward
** the hydraulic system is blocked at one or more locations due to mineral sediment. Find the location and cause of the block and correct it.
** Clean the brew unit (see cleaning instructions) and make sure that
a- the ground coffee used is not powdery fine.
b- The dose of coffee grounds is not in excess specification
c- check if there is blockage. Find the cause and remove it.
8- If steam and hot water flow is normal, but the ventilate sign persists, then the flow meter or the electronic control board is bad. Replace flow meter or the control board, as necessary.

Try also the following:

  • Press hot water button once. Message on the screen will not change, this is normal.
  • Open the steam knob and allow the water to flow freely from steam wand into a cup. The screen should now read "Hot water,ventilate", you may need yo empty several cups of water before message changes. In some case it is necessary to refill the machine container without interrupting the operation.
  • As soon as the screen displays "hot water," turn the steam valve off .
  • If the machine warms up again, then problem is fixed.

Hot Water Steam Efficiency Plus Comfort


Steam heat is a great warm, wonderful, and absolutely fabulous way to heat your house. Steam heat is almost always created from water in a boiler fueled by gas, oil or electricity. It then passes through pipes and radiators or convectors to heat your home. A steam heating system uses steam that is generated from a boiler. When the water boils, the steam rises through the pipes and into the radiators to heat them. The hot radiators then heat your home.

Steam is a great heat distribution medium because it moves easily through your system and it has an extremely high heat-holding capacity. The heat-holding capacity of steam is much greater than that of water. Steam heating systems often operate at very low pressures and usually under 220°F. Steam heat is usually distributed by either one or two pipe systems. In a case of a one-pipe steam heating system, a single main serves the dual purpose of supplying steam to the heat exchanger and allowing condensate to run back from the radiators also. A two-pipe system has two connections from each heat exchanger or radiator. In this system, steam and condensate flow in separate piping from each other. With a steam system all pipes must be well insulated and you must use pipe insulation rated for steam piping. If the insulation is removed the system will no longer work as designed. Noise and all sorts of problems will come from uninsulated piping.

When you have radiators on upper floors or radiators that are further from the boiler they should be adjusted to release more air to compensate for the increased air volume in the piping due to the distance from the boiler. If you have a valve that is clogged with mineral deposits or stuck shut, no air will be able to get out of the piping. Because of this no steam can enter the radiator, so it doesn't heat up. This will block the movement of steam into the radiator, or cause a very noisy hammering as pressurized steam tries to get through this water "dam".

Steam radiators need to have a valve that allows air to escape at a controlled rate so that the radiator can heat up. Steam heating systems will also lose a little bit of water all the time, so there has to be water makeup so that you do not run your boiler dry. Steam heating systems without an automatic water feeder are not safe. You will risk serious boiler damage should boiler water be lost. If the boiler runs dry it could also explode if water is placed into it while it is hot. There should always be a low water cutoff installed on every steam system. Therefore on a steam boiler the automatic water feeder serves as a safety device also.

It is very important that you find someone that is very familiar with steam heating systems when repairing or installing steam heating. Incorrectly designed, installed, steam systems and condensate piping is a huge problem in today's buildings and facilities. There are not many qualified to design and install properly operating steam heating systems. Incorrect steam piping will always cause costly premature failure of steam equipment such as steam coils, heat exchangers, and control valves. Not to mention the higher cost of operating a system that is not working efficiently.

If it is a 5KES100 model then yes that's how you do it, you get your hot water from the steam boiler so the steam needs to be released before the water can come through. Turn the tap wide open and press and hold the steamer pump button. The rush of steam on full open is short lived.

I have a 10 year old Burnham Model 3WNH, and was told that I could get hot water for showering from it. Is this possible? I do see a 2 1/2" knock out on the back.


House hold hot water is a common addition to boilers. Some, not all have it as an option.

The problem I'm having with your question is the model number. I don't find that number anywhere. Can you check that again please?

I have a 5 -7 yr old burnham gas burner for steam heat. I am frequently needing to put more water than normal and notice the pipes bang now also,what do you think could be wrong? thank you


When was the last time the unit was drained and flushed? Also the feeder may be stuck closed if it has one. Check all the steam vents to make sure thay are letting steam out of them. If not, replace the ones that are not. The banging is thermal shock (Steam hitting cooler water in the pipes). For some reason all the water may not be draining back to boiler.

Boilers do not filter air, as they heat with water.... Most boilers do not require home owner manitenance, unless your circulators need to be oiled

I'm a new plumber. I was asked to restart a burnham gas fired steam boiler in a fire damaged apartment. The boiler was drained last winter along with the radiators but was not winerized. I am their plumber...


1. You need to fill the entire system with water before you fire it, boiler AND radiators... Then, you would normally vent as much of the trapped air in the system as you could... It's not like you are only going to fill just the boiler and then pump that water through the pipes.

There is a temp setting on the boiler, but I don't think that's a solution. Remember that the water in the system is going to begin circulating as soon as you start the boiler. So, it will start circulating when it's cold, and then gradually warm up.

Your problem is not the sudden rush of hot water, it's going to be filling the system in the first place, and getting the boiler started before the system freezes up ...

I don't really have any suggestions for you though, other than perhaps renting one of those construction heaters ... and bring the building temp up a bit. But there's certain dangers associated with them too... Carbon Monoxide for one, fire is another (if used improperly).

Just thought of something: Fill the system with glycol based anti-freeze solution that's designed for heating systems. That oughta do it...

I'm guessing there's not a functioning water heater either at this point, is there ? If there was, you could possibly rig something up to fill the system with lukewarm water, and fire it before it freezes up.

2. You don't have a lot of choice. You have to fill the system, fire the boiler & wait.
It is going to take a long time to get the system up to temperature. Instant circulation is a double edged sword. The upside is you get a little bit of heat into the water & have it moving making freezing less likely. The downside is, it's hard on the boiler with that much cold water coming back you are likely to have condensation.
