Im assuming you tried it more than once and the tank is full when you start? If your doing manual fill pour over the timer has nothing to do with that. If it's plumbed with a water line, before you start changing your timer for the brew cycle, first try the easy fix which is unscrew the spray head. it's the piece the water comes out to the basket. Take the cleaning spring tool and rotate it as you push it thru the tube you just unscrew the spray head from. As your pushing it thru it has two turns in it . Just rotate and push until you have gone thru the second one and then it's clear to the water tank. Unfortunately this doesn't always get it unplugged. Where the tube goes into the water tank there is silicone hub on the part that's in the tank and it can keep some of the lime buildup from being removed. You will have to take the top off and remove the tube to clean it if that happenes. Dont forget to unplug it first. The other common spot for a restriction is where the water leaves the pan your pouring into. You need to remove the pan to get the spray tube out anyway so look also at the big nut that holds the pan onto the tank.sometimes the hole will plug in the center .

test element for failure

Couple of ideas.

Your weak coffee could be due to the machine not getting hot enough, which is usually caused by calcium scale buildup on the heating element (the "burner").

Try descaling with a citric-acid based cleaner, such as Dezcal or Durgol.

The second is the coffee your using is a weak blend. Try changing to a different coffee and see if the strength is better.

This sounds like the light flickering rather than a faulty connection. You can check for a bad connection by tuning a nearby radio receiver to no station in the AM band. If there is a bad connection causing this you'll hear the sparking (in time with the flickering) on the radio.
Flickering is a common effect seen with neon indicator lights when they age and does not affect the switch function at all, so can be safely ignored.

The water inlet valve may be stuck open from mineral deposits. You can get rebuild kits for the older ones or just replace the valve?

If all passages are not plugged up it should flow through with or without heat in the tank.

Underneath the warming plate is a element assembly that will have 1 or 2 thermal fuses and a temp sensor. If any of these have faulted that condition will arise.
I suspect that the temperature sensor is 'sticking' in the open position. If you remove the bottom cover (while unplugged of course) and lightly tap the sensor with your screwdriver it may remedy the issue for awhile but the initial cause of the problem will still exist. If the brewer is worth it you can replace the sensor otherwise it may just be cheaper to recycle it.

A model number would be nice but since all (drip) coffee makers are generally the same in principle I'd wager it's your temperature sensor (underneath the heating plate) or when you plugged it in voltage escaped through the switch causing the unit to be 'on'. Think of a coffee maker like the first 1/2 of a steam engine. Water from the reservoir gets converted into steam by a burner (also warms the heating plate for the carafe) and instead of the steam driving components it gets condensed above the coffee grounds. Without that temperature sensor the burner would be going 'full blast' all the time and burn your coffee which is why a broken sensor will cause a 'no heat at all' issue while a failing one can give false signals to the control board. I hope this narrows down your issue and good luck!
