SOURCE: boiler loosing pressur

generally preesure problems are caused by the following- obviously a leak, bleeding of rads without topping up the pressure, pressure relief valve passing( probably an integral part to the boiler), or potentially a problem with the expansion vesell.
the expansion vessel is a tank which
holds water and air- it should be pressurised with air by about 10 psi or up to 1bar, if the diaphragm has split this ill cause pressure problems all day long

hope this info helps

SOURCE: loud noise from the freezer side

The problem is a buildup of ice on the plastic housing (the curved plastic bit) in the back of the freezer under the fixed shelf where the icetub goes. The fan behind this plastic housing is hitting the ice when the defrost comes on.

Unplug the fridge, unpack the freezer, remove the four screws in the back, take off the sheetmetal backing and let the fridge thaw. You can remove the plastic piece after a while and get the ice off (be careful not to remove the styrofoam insulation by going too quickly).

Reassemble and you're back in business, for a few months. I'm never buying Samsung again myself.

SOURCE: fan making loud noise

Hi

does the noise start as soon as you turn the fan oven on?
does the noise stop as you turn off?
just depending what make and model you have there is two fans
in it 1 is the fan motor inside oven at back and other
is the cooling fan which is at top of oven .you just need
to find out which one it is and just replace . then should be back to normal

When it is brewing it make a loud noise during the brewing


Any coffee brewer will bring water to a boil and expel the hot water over grounds or into a container. This water is sometimes under great steam pressure and is released by the user with a knob, handle, etc. These pressurised machines all make noises but should be within the normal operating range while using the machine. If it makes noise other than when in use then there may be an issue. Have a technician check for safety reasons as you are dealing with a 'steam BOILER' . For drip makers there should be no pressure other than the normal 'glug-glug' sounds while brewing. A commercial brewer will just have water sprinkling down into the basket and possible 'whine' noise as the tank refills. But if it's not your normal noise then have a tech check it out. ukeboy2@yahoo.com

Ideal response combi boiler model 120 loud vivrating / high pressure/ zero pressure


the low pressure issue is most likely the expansion vessel needs repressuring because the valve has leaked and is not seating properly so causing water leak outside.- with the pressure on zero, drain about 1/2 bucket out, mine had a exit tap near the inlet tap, then attach a car pressure gauge/ pump to the top of the orange exp vessel. pump it up to about 1.5 bar, that should do it..you may have to do this 2 or 3 times..
re loud rumbling sound, mine had this too, and at around the same time ! heres how to fix it..
BGas engineers are lazy, and unless you watch em like a hawk they lie about changing a part...mine had this loud noise problem and its caused by the gas being deflected out, because it has not been ignited by the spark electrodes, and the rubbish boiler doesnt detect this quick enough, so some gas gets out ..You may be able to smell some gas too. The cover is supposed to stop this, but it dont.

with power isolated, all you have to do is carefully remove the fan, and then the burner, and then dry it, clean it, and adjust the electrodes, 5mm gap between the pair of spark electrodes, and 7mm gap to the cone. and 7mm for the sensor electrode. Mine had a bit of water, i think its from the condensation coming back down the flue ? because the exchanger looked ok.

Also be careful of knocking the sensors and wires, and also check if these are ok as well.
This is a very common issue and nobody tells you

My unit outside is working fine but it is making a lot of noise. All my neighbors are telling me that this is not normal. What can I do to reduce the noise. It is spinning fine but it makes loud noise.


Is the condenser coils clean..... If not take a hose and wash the condenser coils But make sure you shut the Main power off to it. Has the unit been charged with Freon lately??? If so they may have gotten it overcharged which will cause High head pressure and make the compressor noisy..... Or is it out of level and not setting on a stable surface. causing a vibration noise. You can put rubber pads under the AC if it is a vibration noise...... Also the Compressor may be going out..... It is hard to tell with out hearing it first hand....Hope this helps If you can't get it to quite down I would setup a Service Call to have them Service the AC and that you are having a loud noise coming from the unit....

It is making a very loud noise when filling the boiler. Had a coffee repair man look at it . Not solved


my astoria espresso machine is also making a loud noise when running ( brewing espresso ) ...it only happens under pressure and does NOT happen if its running but there is no espresso ( not under pressure ) .... my guess is that its the solenoids.... if you find out what is causing your problems please let me know...

Yesterday my ariston boiler made a loud noise and water burst out from the boiler what can be the problem?


Hi,
The pressure built up in the boiler and the relief (safety) valve released some water to relieve the pressure...
Either the exspansion tank is bad or the fill valve is leaking by...
This causes excess pressure to build in the boiler...

Greenstar 30CDi conventional condensing boiler and the temperature is fluctuating rapidly and repeatedly between 37 and 63 degrees. It is set on 4 so just above 60 sounds correct according to manual....


It sounds like you have air in the system, Turn Boiler Off keep pump running and try to find a spot where you can bleed the air out.

If you dont have an automatic water fill installed then
you will have to add water by hand

Optimax he 31 c whirs loudly but makes no heat


After calling an engineer it turns out it was a faulty fan (The loud whirring should have given this away...) Apparently this is a relatively common fault with this type of boiler. Only solution is to replace the fan which, as of 2010 is still under warranty and can't be bought separately, so you'll need to call Ferrolli.
