I have a Ariston MicroGeenus HE 24 HFFI boiler and the error message A077 keeps coming up when we set the timer programme. I have reset the system and it works on constant but after a while the system turns itself off again and the same error message appears

SOURCE: ariston micro genus combi boiler

having found a circuit diagram, realised that the divertor valve was electrically operated.i unplugged this then unclipped the motor from the valve body,the diverter valve is spring loaded and once i'd removed the motor the spring raised the valve to divert water through the dhw heat exchanger,giving us hot water but no heating, if i refit the motor the problem comes back heating no dhw.ordered new motorised valve assembly £30 next day order .
this was a simple fix without having to drain the system down.

SOURCE: ariston genus premium 24 error

Code 101 is related to connection between pcb and boiler unit.check if the electrodes are still sparking even after the gas had lit, this means the pcb is not detecting the flame and trying to relight.Try reset, If operation is blocked, the display shows the text RESET and the relevant error code. To restore boiler operation, simply press the RESET button on the control panel. If still the same error is coming up then turn the unit off for 1 hour then restart it again and check.If still the same error is coming up then press the "INFO TOP" button on the system .Simply by repeatedly pressing the "INFO TOP" button, the user may immediately view a whole range of information which is necessary to the correct operation of the boiler.---------If the reset is not helping and still the error is coming up again then the pcb has to be checked to resolve the problem.-----------Thanks.Helpmech.

SOURCE: my boiler heating is working

As I understand your question, you have a boiler with a 'summer/winter' hookup for domestic hot water.

Your boiler should run all the time, i.e. not be shut off by you. Your boiler provides hot water for baseboard heat in your home ... possibly through several 'zones' each controlled by an individual thermostat and circulator. Yours may be a steam system. If this is the case, you have radiators not radiant baseboard heaters and no circulators.

Your summer/winter hookup provides a constant supply of domestic hot water. It does this by taking cold water from your water main and passing it through a copper coil which sits inside your boiler and then to your hot water main in your home. Since the coil sits in the hot water at the top of the boiler, it is constantly being heated. This coil may be in a deteriorated condition in your case or it may be too small for your needs.

Several years ago, I did a small upgrade to my mid 1950's era American Standard boiler. The summer winter hookup in my case was mounted on a 4 inch cast iron boiler plug. The coil was 12 feet long (folded up to a package about 1 foot long). I was very afraid when the plumber came in with what amounted to a 10 foot long pipe wrench. My fear was I would have a pile of broken cast iron at the end of the day. All is well that ends well. He got the old one out and replaced it with a coil that consisted of 20 feet of copper tubing 3/4 inch in size (the folded tubing was about 20 inches long and fit nicely into the boiler). We now have all the hot water a household consisting of one guy and three gals would need in all but the extremest of times..

I think you r answer is here ... replace your summer/winter coil with a new, bigger coil.

Something else I did. My kitchen is 60 feet (pipe wise) from the boiler. It takes a long time to get hot water there. I put in a small electric hot water heater just under the kitchen. I put a timer on it so it runs for a couple hours in the morning and a few hours in the afternoon. The hot water line from the boiler serves as the cold water input to the heater. I now enjoy the convenience of quick hot water in the kitchen with the relatively low cost of oil heated water from the boiler as a relatively small cost of electricity.

My winter settings are 160 - 200 and my summer settings are 120 - 150 which seems adequate for our needs.

Thanks for your question at FixYa.com. I hope I have been of assistance to you today.

The boiler wont fire up and the blue light flashes once per second


Let's see what we can do to trouble-shoot this boiler--

First of all-- Are we talking about a Hot Water 'Boiler'-- In other words does this boiler heat water that circulates thru the house, to keep you warm?

Next-- What is your fuel?

Have you Shut the system down, to reset it?-- What happens when it comes back on again?-- Clicking sounds-- pumps trying to start-- solenoids trying to open, etc.-- Tell us what you observe-- so we can help you trouble shoot this problem.

I have a Powermax 155 boiler that keeps losing pressure. Most of the time, I can usually work around this by closing the tap in the boiler until the pressure rises, but it's not working this time. I...


I would first check the switch on the front to ensure it is set for CH & Water. Push bottom of the switch, check you have a pressure of 1 bar on the gauge to the left of the front panel. If not, top up until it gets to 1 bar. Ensure a demand is being called for (the timer is asking for heat) by pushing the CH button until the grey line is alongside 24 hr. then check if the central heating pump vibrating. If still not come back to me for more info

The boiler does not fire when hot water is selected although the red light is on. However the boiler fires ok when central heating is switched on and this does then heat the water. Is the problem in the...


Hi. and you are correct, if the boiler fires when the controller is set for central heating to come on, but does not fire when calling for hot water, the controller is either faulty, or not programmed properly. This is what tells the boiler to do on command, so, this is all that it could be.If you no anything about this controller as far as how it is set up, is it a programmable one, voltage on it, does it have wiring terminals on it that are labeled and can you get to them? If you can, and the wires are labeled, you can jumper them out to see if you can bypass the circuitry and get it to fire up on a call for hot water. This is the way to test it, very easy. You have to look at the wiring schematics to find the wires that are 1-hot and 2- hot water control. Jump across the 2 wires and if it fires, the controller is faulty. Careful if this is a high voltage controller as 120/208/230 volt. Check this out first. It can still be done, you just have to be careful not to ground yourself out. It maybe 24 volts. If it is higher voltage, you can kill power and get a insulated lead/jumper wire with clips on each end. Clip them to the terminals you want to jump out and turn on power. This way you are not touching anything. Please let me know the outcome on this and please when rating me as being helpful to you, be kind. I thank you. I will be here if you have more questions or need my help.

No heating and no hot water, my boiler won't fire up


If there is a hi-limit switch, maybe it's open, reset the switch, and monitor the temperature, if the temp. increases over the set temp. replace stat, and clean lime off from the tank, if does not have a filtering system

Central heating system boiling


more information required but if the boiler supplies the domestic hot water cylinder then the stat on the cylinder may be bringing on the boiler also the boiler stat may be up too high try turning it down.

My aristion DIA 20-24 combi boiler keeps tripping the over heat thermostat button located under the main control panel maybe 5 times a day seems to be getting more frequent


hi,

just check your water supply of your aristion DIA 20-24 combi boiler if is in constant pressure. not properly circulated water supply can cause overheating.

and manuals can help us also in proper checking. at the link below please check this out if you don't have.

Is this a water circulating system? If so there are bleeder ports on your radiant heating zones on the floor that you can bleed the air out of the system. They look like a tire air pressure valve. Depress the valve core with a small screwdriver or something of the same nature. You will hear air coming out and water will come out. This is done while system is running. Also it may maybe under pressurized, circulating pump could be shutting down. Does the boiler keep running or shut down on reset. If it does could be within the boiler itself. Please rsvp with more info.
