How do I clear a Breville espresso machine Er05 error after cleaning?
Answer
Er05 on many Breville espresso machines points to a sensor, thermoblock, or steam/espresso circuit fault that cleaning alone may not clear. Run the machine’s official troubleshooting or descale/clean cycle first; if Er05 returns, the machine usually needs service rather than a permanent bypass.
Before you start: stop right away if…
- Espresso machines use high heat and pressurized water; unplug and allow cooling before any inspection.
Follow these steps
Power-reset the machine
Turn the machine off, unplug it for at least 60 seconds, plug it back in, and power on while watching whether Er05 returns immediately.
You should see: The code either clears temporarily or reappears right away, which helps gauge a hard fault.
Run the official clean or descale process
Follow the clean/descale instructions for your exact Breville model with the recommended solution and water tank level. Do not skip rinse cycles.
You should see: The clean cycle completes and the display returns to a normal ready state, or Er05 interrupts again.
Inspect simple blockages only
With the machine unplugged and cool, empty and rinse the water tank, drip tray, and any user-removable filters or group-head baskets for scale or debris, then reassemble firmly.
You should see: Water path parts are clean and seated; after powering on you can retest espresso.
Stop bypass attempts and arrange service
If Er05 continues, stop trying to bypass the code to force espresso-only use. Contact Breville support or an authorized service provider with the model number and error code.
You should see: You receive a parts/service path instead of running a machine with an active sensor or heat fault.

Extra tips
What to look for: Exact code Er05 on the display, whether it appears at power-on or during espresso/steam use, and any other codes shown.
Before you change anything: Unplug the machine before inspecting tanks, valves, or removable parts. Use only the cleaners Breville recommends for your model. Do not dismantle sealed heating components. Note the full model number from the sticker for parts or warranty help.
