TRANSCRIPT
Purpose/Scope:
This slide presentation covers three processes; Disassembly, Pump Replacement, and Reassembly.
The slides are in order first for Disassembly, then Pump Replacement, and in reverse order for Reassembly.
Some slides are positioned in order for Reassembly, so they appear among but are marginally relevant to the Disassembly process.
Color Coding of slide text is as follows:
Disassembly – slide symbol:
Pump Replacement – slide symbol:
Reassembly – slide symbol:
Tools Needed:
#1 Phillips/Cross-tip driver
#5 Torx Driver
14mm Open End Wrench
Slip-Joint Pliers
Ulka EAXP 115VAC (or 220VAC) Pump
Teflon Tape
Small-tipped electronics vacuum (grounded to prevent static charges on the tip) - optional
Spray-and-wipe cleaner – optional, but... please...
Lint-Free Rags or Towels
Frother Steam Control Knob
For Disassembly: I took
off the frother knob by
simply pulling it
straight outward
For Reassembly: There
is a key on the post
(shown here at the top
of the hexagonal post)
and slot in the knob.
Align the key and slot
and press to fit.
Frother Steam Control Knob
For Reassembly:
Steam Control Knob
in the off or closed
position.
Frother Steam Control Knob
For Reassembly:
Ensure the steam
control will pass
through its entire
range.
Steam control knob in
the on or open
position.
Frother Tube Disassembly
For Disassembly: I unscrewed
the keeper ring on the frother
tube, pulling all the pieces
down and off.
For Reassembly: note the rings
on the tube (hard to see in this
picture), placing the parts in
place to just cover them when
it is all screwed finger-tight.
This is a plastic nut, and will
break if over-tightened. It is
not a flight risk. Finger snug
does it.
Frother Handle
For Disassembly: I pulled the
frother handle off. It is
friction-fit, so just pull it out
with a bit of an upward
motion while pushing back
against the tube below it.
For Reassembly: Set the tube
all the way down and press
the handle back on, making
sure not to pinch or overly-
stretch any of the legs.

Front Left Corner Screw
Under Water Tank Torx Screw 1
I didn’t anticipate Torx screws,
so only brought a #1 Phillips
driver from the shop to my
desk. Like so very many things
in my engineering world, life
would not be complete without
a Leatherman. My Surge
being out for repair, I used my
ready-standby Charge TTi
with the handy bit holder and
Torx bits available from
www.leatherman.com – ever
ready at my hip – to manage
the surprise Torx screw
removal.

Grind Selector Removal
For Disassembly: The
grinder fine/coarse
adjuster had to be
lifted off its pins – it
is just pressed down
into the guide holes.
Grind Selector Reassembly
For Reassembly:
align the dots
and press the
handle in place
centered on them.
Rear Right Lid Screw
Lift off the lid
For Disassembly: Then it was
just lifting it clear of the
electronics panel and the
frother tube, which I pushed
up as I pulled up and slightly
forward (to get around the
tabbed front edge screws)
on the lid, and setting it
aside being careful of the
wires.
For Reassembly: Fit the lid
over all, avoiding pinched
wires and tubes.
Pump Removal
The two white-shelled spade-lugged
wires on the pump are AC power, so
they are not specific to which post
they are attached.
Reach a finger around below the
ends of the motor assembly just next
to the black rubber mount brackets.
Mash the release buttons, and push
the motor mounts forward and aft,
away from the motor, to clear their
clips. Pull the friction-fit nipple off
the inlet side, remove the hold-down
kotter pin in the out-flow tube and
extricate the tube, and lift out the
pump.
A 14mm wrench and pliers takes the
pump apart from the output
manifold.

Pump Reassembly
A small-tipped vacuum was handy to
clean up the compartment before
reassembly.
I used two wraps of Teflon tape to
help the pump seal to the output
manifold, and again I was careful
not to over-tighten the brass threads,
leaving out the pliers and using my
hand and the wrench to snug the fit.
The black and white wires to the
vibratory pump provide alternating
current (AC) power, so are not
polarity-specific – they don’t care
which wire is attached to which post.
Reassembly
Reverse the Disassembly process, taking special
note of the slides with orange Reassembly
instructions.
Clean as you go with a small-tipped vacuum for
reaching into tight spaces – I use a purpose-built
electronics vacuum that is grounded so I don’t cause
electrostatic shocks to electronic components – and
spray-and-wipe cleaner with lint-free rags or
towels.
Coffee Time!!!
