WATER RESERVOIR
1. Remove and clean the water reservoir periodically with warm
soapy water. To remove the reservoir, take off the reservoir
cover and lift the reservoir up by the two black handles – a rm
upwards movement.
2. When returning the reservoir, ensure you press down rmly so
that the tank plug at the bottom is fully engaged.
3. Use fresh, ltered water to ll the reservoir. Do not use distilled
water.
DRIP TRAY
1. Remove the drip tray and wash with hot soapy water. Rinse, dry
and return.
BODYWORK
1. Wipe the stainless steel surfaces with a soft, non-abrasive and
damp cloth. Polish using a dry, soft cloth. The Rocket Espresso
supplied stainless steel cloth is best for the cleaning of your
machine body work. We do not recommend using any of the
commercial stainless steel cleaners.
DESCALING
1. Rocket Espresso do not recommend descaling your espresso
machine.
2. Many of the chemicals used to descale espresso machines are
particularly aggressive. These chemicals can cause internal
corrosion of hard metals used in the construction of the machine.
3. Additionally it is very difcult to remove all the descaling solution
from the machine once the procedure is completed.
4. Control the quality of the water you use in the machine, always
using a ltered water. Distilled water may lack the necessary
conductivity required for various electronic functions needed in
the operation of the machine.
5. Additionally where possible try to use the Rocket Espresso
reservoir lter.
TROUBLESHOOTING
EXTRACTION IS TOO FAST
• Check the lter basket is not under-dosed.
• Check the grind is not too coarse.
EXTRACTION IS TOO SLOW
• Check the lter basket is not overfull.
• Check the grind is not too ne.
• Check the shower foil is not blocked - it may need to be back
ushed or removed and cleaned.
• Check the spout of the handle is not blocked. If it is dirty with
rancid coffee oil, it will need to be soaked in a solution of espresso
head cleaning shampoo and water.
WATER ESCAPING FROM AROUND THE HANDLE
• Check the head seals. If they have dried out, they will need to be
replaced.
• Ensure the group handles are kept in place whenever the machine
is not in use, as this will help to protect the seals.
ESPRESSO TOO COLD
• Check the cups are warm. You can heat your cups by pouring
hot water into them, and then discarding it, before you start the
extraction.
• Too much water may have been drawn from the group head.
Let the machine rest and limit the amount of water drawn
from it between extractions to ensure the machine remains at
temperature.
ESPRESSO TASTES BITTER
• Extraction may be too slow. Check the grind is not too ne.
Correct the dose and make it coarser.
• The machine may be dirty. Back ush and clean the group head.
Clean the group handles and lter baskets.
