The blue power on light does not light up when pressed on my Kitchenaid KES100 espresso machine although the high pressure pump runs when the button is pressed. Neither boiler heats up.

You will need to test for where the power stops & check the fuses on each boiler for continuity. If you find any blown then replace the thermostat on that boiler along with the fuses. The thermostats are different rating for each boiler, don't mix them up. It's highly unusual for both boilers to fail at the same time. Occasionally one of the boiler elements can fail, there are 2 elements on each boiler, check them for continuity. If you have any boiler leaks then replace all the seals on that boiler, the steam one is the one most likely to leak. Buy your own seals using the old ones as samples from someone specialising in O ring supply. There are 5 seals on each boiler. Do not purchase rubber or silicone seals, only use Viton seals, they are high temperature.

SOURCE: Kitchenaid Espresso maker no longer dispenses hot water from frother

by frother you mean it puts out steam ? if yes then I need to know how long you hold down the button and have you checked the hose in back to see if it has cracks or is kinked?

SOURCE: Vaillant boiler (VCW GB 221)

The movement of the diverter valve is critical on this appliance, and is located on rear right of the boiler, when hot water is turned on, theres are two microswitches, which must break (they both close in Central heating mode), if pump is running, it is recognising the hot water demand, check microswitches are breaking, if not, it tends to be a defective servo valve (located above the water valve), or a blocked/ restricted control line (small copper tubes which connect into the servo valve)

It is clear that there is a problem with water supply. Check if pump works, if it does, there is blockage in water supply to pump. Check and clean.

The clue here is that the problem involves the hot wate and the single or double espressos. These three functions require accurate water measurements and they are programmable. It appears that the flow meter is not sending the correct information to the control unit. This could happen if you have blockages or if the flow meter is not working anymore. Most likely you need a new flow meter which only costs about $20 and should not be too difficult to replace. It is located between the water tank and the pump.

Gary,

I have the same exact problem with mine starting today, did you get this figured out? I'd love to know if it's fixable or not as I was planning on selling my previous machine. If it's an expensive repair, I'll just have to ditch this one and go back to my previous one.

HI I have a Kitchenaid artisan espresso machine it makes a very load noise when I press the buttons for coffee and froth any suggestions ? thank you


You don't say if there is any water flowing along with the loud noise. If there is none then my suggestion would be that it's a dry water pump so you will need to force some water up the clear pickup tube into the pump while it's making that loud noise. The pump valves will be dry.

I need a new internal switch for kitchenaid artisan coffee machine what website do I use. Can only find external parts. Sam


There are several switches inside one of those if it is model KES100. Best to supply model number and say which switch it is, without looking I can think of 4 switches off the top of my head. I'm in New Zealand and have 3 of them in stock.

Coffee machine gage that doesent move


If the model is KES100 and coffee and steam are both at normal temperature then the problem is one of the following
1) The needle has come loose on the shaft. Solution; turn machine on and press needle back onto shaft in the usual position for full heat when the machine is on full heat.
2) The gas/liquid has escaped from the copper tubing to the gauge. Solution; fit a new gauge assembly.

Although machine is turned off water pumps through to the over flow tray(power button is not pushed on )


Sounds like a check valve on the pump or the power switch is not operating properly, if off and pump is still working.

The blue light is blinking, the water tank is full, but the water isn't heating up at all. should we return it? Or is there something that we missed? We followed the instructions and are getting no where.


blinking light means the water circuit requires priming.
1 - press power button.
2 - place a cup under steamer and turn on full.
3 - turn steam off when blue light stops blinking (probably a few ounces of water in your cup).
4 - you're ready to rock!

Your thermostat has failed. The middle button is the pump. The bottom button is for the steam mode. If you are getting steam instead of hot water when using the pump, then the boiler is way too hot. Either adjust the thermostat or try descaling the boiler.

Makes espresso, coffee, water, but will not steam


The pump has gone bad - through use. This is a common problem, and has to do with the "seals" that are in the pump. Since the pump generates high pressure and heat, over time, the seals will fail, and will be unable to generate enough pressure and heat to create steam. The only remedy is to have the pump replaced through the Breville Out of Warranty repair centers.
