Noise A loud ** clic* is heard every 5 second ????

Possible the swinging fins jammed up. Turn it back on and watch the swing. Not very many moving parts. If it's the blower wheel you will know!!

You are going to have to remove the spray bars and the filter at the top of the pump housing to see if something is stuck in the pump

It would point to the element going .

Ur colors wheel is dead.Replaced the colors wheel.U have no tech.skill don't tries to replaced the colors wheel,because have to take alots of boards parts,and manchanics parts to get to the colors wheel.

if you've got a few $$ to risk ,try some synthetic oil with new filter ...it often work good for these kind of noise as long as it is not a loud knoking nois ...if it is only a fast clic clic nois it will probably work!

Sounds like the gear is failing in the ice maker unit. I would replace it.

This is a very loud machine. Here's the normal operation: You turn it on, and wait a few minutes for it to heat up, at which point the heating light will go off. Then make sure the function knob is turned to coffee, and it will start brewing. At first, it will make a short (loud) sound and then stop for a second. The purpose behind this is that the machine is pre-wetting the coffee, so that steam can more easily shoot through it in a couple of seconds. Then the loud noise will start again and run continuously until you turn the function knob back to the center. So, the sounds you were hearing were normal. There is a delay between when you hear the sounds and the water starts flowing out. If the coffee is pressed down (tamped) too hard, that delay will be longer. Hope this helps. You made a much better choice purchasing this machine rather than the more expensive EM-200, in my opinion.

Sounds like you need to replace your coils. Probably only one of them is bad, but why hassle with determining which one when you can get a pair for about $20 (the other one may be ready to fail soon anyway).

never had that problem with my GS400 but on my 95 maxima, i used to have that same high pitch squealing noise... i used some belt dressing that i got from R & S Strauss for a few dollars and sprayed it on my belts and pulleys that ran around the alternator, compressor, etc. and never heard the noise again. hope your problem is as simple and cheap to fix as mine was

Are you sure this noise is not just the ice maker trying to cycle without water? If it is not turned off it will dry cycle every 15 min or so.
