Question about Isomac Tea Espresso Machine

1 Answer

Red boiler light will not go on. The boiler does heat up.

This was intermittent before. I would turn the switch on and find the red boiler light would go out while the machine was heating up. The built up pressure would start to drop. I would flick the power switch on and off and found the red light would eventually go on. The boiler heated normally after that. The red and the green boiler lights worked properly. Now the switching on and off doesn't work. The main power light turns on and the machine will warm up slightly but the red boiler light and the boiler are not working. I checked inside for loose wires but found nothing. The machine has been used every morning for the last 10 years and has worked fine. I would appreciate any thoughts....Thanks

Open the steam valve when you turn the machine on that will vent out the boiler, keep it open until it starts to hiss slightly and produce small steam bubbles, then close and machine should heat to temp. If that solves your problem then the vent valve needs to be replaced, until then you can turn using the steam valve open trick.

I have a Siemens RWB27 thermostat linking to our combi-boiler. It is showing the on/off display but the red light is not on. The boiler is not corresponding to the on/off times. Any idea how to fix?

with the limtied informton I have, Ill try my best to answer what I can. Being a compi boiler, I assume this means it heats yoiur hous e AND your potable water. The way it works, depending on the time of year, It may also have an indoor/outdoor recept control that alows the boiler to heat the house at a certain temp, about 45f, in the fall and spring. If the tstat giets its power from batteries, kill power to the unit at the breaker and change the batteries, turn unit back on and reset tstat. If the unit gets power from the boiler itself, kill power, wait three minutes, turn back on, WHILE you have someone whatching thr red light. This light could be a codeand/or fault indicator. If the light does do something differant but still wont work, watch exactly what it does,i.g., change color, or blink in a certain sequence i.g. 2 on 3off 1 on till it repeats itself. You can find the meaning of the code on the inside of the boiler door or the manual itself. It could be as simple as bad batteries, but this is uncommon. to find out, if you have multiple stats, be sure you have your main stat, as the others are slaves, doing what the main says. when your sure you have the main, pull it off the backplate attacheg to the wall and very carfully 'jump' a wire between 'r' and w. R-24 volt ac power, W- heating circuit, G-fan( if applicable) c - COMMON, if stat gets power from boiler.Y is for ac. If this is your first attempt at startup, have a qualified service tech chech it over. Is there a chance this is a heat-pump type? for more pertinant information

No water/coffee comes through? the temprature indicators doesnt light up?

The POWER LIGHT for the 889 is RED and located on the LEFT of the center cowling

The BOILER LIGHT for the 889 is YELLOW and located on the RIGHT of the center cowling

If you turn on the power to the unit (the INNER SWITCH on the RIGHT SIDE) the RED light should turn on, showing that the machine is powered. At that point the YELLOW light should also turn on for about 10 seconds, at which point it will turn OFF with an audible CLICK.

If the RED light does not turn on then you have a very dead machine.

If the RED light does turn on but the YELLOW light does not then you have a half dead machine.

Opening up and repairing the 889 is not for amateurs. High voltage, heat and pressure inside.

If you decide to bin the machine I would appreciate getting the drip tray from you as I have lost mine.

No hot water

Yes there is a small red breaker switch on the left side of the boiler tank. Unplug the unit first then remove the left side cover and just push down on the red breaker switch to reset it.
