One morning your espresso tastes thin, even though you used the same beans as yesterday. The machine turns on, the water flows, and nothing looks broken.
It’s easy to panic and assume the worst. Most of the time, the fix is simple.
Many common espresso machine problems come from grind size, old beans or buildup inside the machine, not a broken part. This guide walks you through each one before you call a repair shop.

ToggleShort Answer
Most problems trace back to grind size, coffee dose, tamping, stale beans or skipped cleaning and descaling. Adjust those first, and you’ll often fix the issue without a repair.
My top pick for avoiding these problems is the Breville Barista Express Espresso Machine (BES870XL). Its built-in grinder lets you adjust grind size right on the machine, which fixes many taste problems.
How We Chose These Machines
These are research-based picks with 4 stars or more on Amazon and plenty of reviews.
I chose machines that make problems easier to spot and fix, such as an adjustable grinder, a pressure gauge or simple, durable parts.
Quick Comparison Table
1. Weak or Watery Espresso
Weak espresso usually means water ran through the coffee too fast. KitchenAid says a grind that’s too coarse lets water pass too quickly, creating weak or watery shots.
Try a finer grind, check you’re using enough coffee and use fresh beans.
2. Bitter Espresso
If it’s harsh or bitter, the grind may be too fine and the water is moving too slowly. Grind a little coarser and pull another shot.
Old coffee oils in the machine can add bitterness too, so make sure your daily cleaning is up to date.
3. Little or No Crema
Stale beans, a grind that’s too coarse and weak tamping are the usual causes. De’Longhi also lists thinner crema as a sign of limescale buildup inside the machine.
Start with fresh beans, then descale if the problem stays.
4. Steam Wand Not Working
A steam wand not working is usually a clog. Dried milk blocks the tip when the wand isn’t purged and wiped after each use.
Clean the tip, purge the wand and make sure the water tank isn’t low. Mineral buildup can also weaken steam, so descale if cleaning doesn’t help.
5. Espresso Machine Leaking
An espresso machine leaking water often has a simple cause. Check for:
- A water tank that isn’t seated properly.
- An overfilled drip tray.
- A worn gasket around the group head.
- Loose connections.
Reseat the tank and empty the tray first. If it still leaks from inside the machine, contact the manufacturer.
6. Shots Running Too Slowly
A grind that’s too fine, too much coffee or hard tamping can all slow the flow. KitchenAid notes that sputtering or poor flow can also mean the machine needs descaling.
7. Espresso Machine Not Working at All
If your espresso machine not working means no power, start with the basics:
- Is the outlet working?
- Is the power cord firmly plugged in?
- Is the water tank seated properly?
- Is an error message showing?
If none of those fix it, check your manual or contact the manufacturer.
When to Call a Professional
Contact the manufacturer or an authorized repair center if the machine leaks inside, shows electrical damage, makes grinding noises from the pump or keeps showing error codes. If it’s still under warranty, don’t open it yourself.
How to Prevent Most Problems
Most of these issues stay away with simple care. Rinse the portafilter, purge the steam wand, empty the drip tray and descale on schedule.

Frequently Asked Questions
Why is my espresso weak?
Usually the grind is too coarse, you used too little coffee or the beans are stale. Adjust one thing at a time.
Why won’t my steam wand make steam?
Dried milk may be blocking the tip, the machine may not be hot yet or scale may be limiting flow. Clean it first, then descale.
Why is my espresso machine leaking?
Check the water tank, drip tray and gaskets first. Most leaks come from one of those.
Can hard water damage my machine?
Yes. Hard water leaves mineral buildup that can slow brewing and weaken steam over time.
How can I make my machine last longer?
Clean it regularly, descale on schedule and fix small issues early. My guide How Long Do Espresso Machines Last? has more tips.
