BCO 330t drip coffee maker troubleshooting

1. The drip coffee takes longer brewing or does not brew at all.

The problem is common for every drip coffee brewing system. Possible cause of improper coffee machine work may become the descale. So your Combi 330t needs to be descaled. You can follow several steps to make proper descaling of the device.

  • pour 4 cups of water into the water tank;
  • dissolve 30 grams of citric acid in the water;
  • put the carafe onto on the hotplate;
  • switch on the device and percolate one cup;
  • switch off the device and leave it for 15 minutes;
  • repeat two previous positions until the water tank is empty;
  • rinse out the system using only water (not less than three times).

Your BCO 330t works properly again. But if not ― you need to go to service center, because there can be other damages that cause the improper work of the coffee maker.

2. Drip coffee has an odd acidic taste

If you notice this after descaling your device make sure that you have descaled and rinse it out properly. Rinse it out again, not less than three times with full water tank. Usually, this step becomes rather helpful in the problem salvation.

3.Your drip coffee maker leaks

bco-330t-_leakingMost leaking problems are not problems at all. Most drip coffee makers are leaking because of too much water in the water tank. If your BCO 330t starts leaking, make sure you have not overfilled the drip coffee carafe. Mind that water level should be not more than 10 cups. If you pour more be ready to have problems.

4. ON/OFF light does not work

Possible cause of the problem may become improper shut off timer set. If your BCO 330t ON/OFF light does not work properly, make sure you set the automatic shut-off timer. If the timer is not set, then do follow several steps:

  • push the ON/OFF button for about two seconds, until the three zeros flash on the display;
  • press repeatedly HOUR and MIN to set time (you can set from 1 minute to 11 hours 59 minutes);
  • wait for 5 seconds after you set the time until the numbers stop flashing.

Mind that while temporary power failure settings are not stored in the device memory.

BCO 330t espresso machine troubleshooting

Espresso is not delivered into the cup
This problem may have three possible causes. First is that it’s not enough water in the tank. If it is so ― fill the water tank and enjoy your coffee.

The second possible cause is that the filter has clogged and blocked the coffee delivery. If the reason is clogged filter then clean it with a pin. But be cautious not to damage it.

The third possible cause of improper espresso delivery into the cup may become the clogging of the filter holder holes. Usually, they are clogging in the spouts and block the coffee, if you brew espresso quite rarely. To solve the problem just clean the filter holder holes.

2. BCO 330t brew espresso for too long

Usually, the cause of the problem consists of the too fine ground coffee beans. But also brewing may become too long because of pressed coffee powder in the filter. To solve the problem, just change your coffee, don’t press it while filling the filter, and put less coffee into the filter. Ordinary, it will be enough to make your coffee machine work properly.

3. BCO 330t stopped frothing milk

There are two possible causes for this problem. First one is that milk is not cold enough. You must know that you have to use only skim milk from the refrigerator. Don’t use hot or boiled milk ― frother won’t work with it. The other reason for the stopped frothing is that cappuccino maker is dirty. To solve this problem, just clean the holes in the frother, but do it thoroughly to avoid the damage of the system.

  1. Unfortunately, these troubleshooting suggestions don’t cover what’s just happened to my combo-delonghi coffee/espresso maker. I programmed the machine to start at a set time (like I usually do) but it never started brewing. The machine has water & coffee and the time including the am/pm designation is correct. I then tried just brewing a pot of coffee (not auto set) and still nothing works. At all! I unplugged the machine over-night to see if it would re-set, or whatever, and still nothing is working.
    Note: I only bought the machine in August of this year (2019).
    Please help!!!

  2. My Delonghi espresso side of the 330t model is not working light comes on for on position but will not steam or froth milk? Other side for coffee works just fine.

  3. Hello,
    My DeLonghi combi bco 330t coffee maker is not working. I put the regular four cups of water and one tablespoon of coffee, but the machine is not percolating.

    Also, recently I had to stop using the expresso option because when I try to use it, water starts leaking all over the place making a big mess (no matter if I put just a little bit of water).

    Any advice will be really appreciated.
    Thank you,

  4. My coffee maker stopped working suddenly. The lights turn on, but the burners do not get hot. Is there something I can do to fix it, or should I just go to another machine. It’s over a year old, possibly just two years old, but I don’t have the receipt to show proof of when I purchased it.

    This is the only coffee maker that I have owned since 2002. They have been, quite simply the best.
