SECTION 02 · WHY US
Four differentiators
02
Bastone and touchpad both
Customers with Mirage Bastone configurations are a small population in LA. We have done enough Bastone work to know its characteristic failure modes — microswitch wear specifically.
03
Pre-2015 legacy support
Brass-fitting era Speedsters and early Mirages. We stock the legacy parts and we know the retrofit paths.
04
Honest about Mirage vs Spirit
Mirage thermo-syphon is gorgeous engineering and a known service surface. Spirit multi-boiler is more set-and-forget. If your bar volume is over 800 shots a day and you want minimal service overhead, we will tell you Spirit is the right call.

Kees van der Westen builds espresso machines by hand in Eindhoven — small batches, exacting tolerances, every part chosen for a functional reason. The owners we service are not casual buyers. They paid $25-60K for a machine and expect the technician to know it. We do.
SECTION 03 · MODELS WE SERVICE
Kees van der Westen line-up
M-01
Mirage (1/2/3-group)
E61-style thermo-syphon, individual heat-exchanger per group. Bastone lever or touchpad activation. Mechanical group-temp adjustment per group. The flagship.
$17-30K new
M-02
Spirit (1/2/3-group)
Multi-boiler with independent brew temperature per group head. Higher peak-volume capability than Mirage. The Spirit Triplette is the high-volume cafe choice.
$26-62K new
M-03
Speedster
Single-group, dual-boiler with progressive paddle pre-infusion. Stainless steel water path (replaced brass in current builds). The collector’s machine.
$16-19K new
M-04
Slim Jim
Newer multi-boiler high-output platform with extensive customization — legs, panels, group choices, colors. Built to evolve with the bar over time.
M-05
Spiritello
Single-group lever machine, dual stainless 316L boilers (more corrosion-resistant than 304). Spirit-class build at single-group scale.
$13-16K new
M-06
Pre-2015 Mirage / Spirit
Earlier electronics, brass water-path components (since updated to stainless). We service these and stock the legacy parts.
SECTION 04 · COMMON PROBLEMS
What goes wrong on a Kees van der Westen
- P-01 $240-$420
Thermo-syphon flow restriction (Mirage)
Mineral buildup in the thermo-syphon loop changes the flow ratio between the two tubes feeding the group. Symptom is brew temperature drift across the day. The restrictor is the engineered choke point and where scale lands first.
- P-02 $160-$240
Bastone lever volumetric drift
The Bastone lever uses a microswitch + flow meter combination for its programmable volumetric stops. Mineral buildup on the flow meter under-counts; symptom is shots running long even though the program looks unchanged.
- P-03 $120-$220
Group temperature inconsistency between groups
Mirage allows mechanical group-temp adjustment per group. After 2-3 years, the adjustment screws can drift from owner-set values. We re-zero them during PM visits with a Scace bench tool.
- P-04 $120-$185
Steam valve seal seep
The flip-flop and tulip steam valves on Mirage hold up well but the lower internal seal eventually weeps. Rebuild kit, 30-minute job per valve.
- P-05 $220-$340
PID sensor lag
Sensor probes age and respond slower; the PID still "works" but boiler temperature swings widen by 1-2°C. Replace at 5-7 years even if no obvious symptom.
- P-06 $420-$680
Pre-2015 brass-fitting corrosion
Older Speedster and Mirage units have brass in the water path (since replaced with stainless in current production). On hard-water installs, brass develops verdigris that contaminates the cup. Worth retrofitting.

SECTION 07 · FAQ
Frequently asked.
Q-01 How much does Kees van der Westen service cost?
Diagnostic and minor repairs run $185-$420. Thermo-syphon work on Mirage runs $240-$420. PID sensor or board replacement runs $280-$520. Diagnostic visit alone is $145 and credits toward the repair.
Q-02 Are you Kees van der Westen authorized?
We service Kees van der Westen machines on-site across SoCal. We are not a Kees-branded service center. The technical manual is available to trained mechanics on request from Kees support; we maintain a working relationship for documentation and unusual parts.
Q-03 My Mirage shots are tasting different through the day. What is happening?
Most likely thermo-syphon flow drift. The two tubes feeding the group head balance flow, and mineral buildup changes the ratio. Symptom is brew temperature drifting 1-3°C across the day. Service interval is every 18-24 months in soft-water LA, every 12 months in hard-water neighborhoods.
Q-04 Can I retrofit my brass-fitting Speedster to stainless?
Yes, and we recommend it on hard-water installs. The retrofit kit replaces the brass elbows, tees, and fittings in the water path with 316L stainless. Job time is 4-6 hours, parts and labor approximately $420-$680.
Q-05 Should I buy Mirage or Spirit?
Honest answer: if your bar serves under 600 shots a day and you have baristas who genuinely care about the craft, Mirage. The thermo-syphon control gives you per-group temperature handles that matter. If you serve over 800 a day or you want lowest service overhead, Spirit. The multi-boiler architecture is more forgiving.
Q-06 How long is a Kees machine going to last?
Kees machines well-watered through their service life routinely run 15-20 years in commercial use. The build quality is genuinely on a different tier. The conversation we have with owners is about water filtration discipline, not about parts wear.
SECTION 08 · CASE STUDY · HONEST OPINION
Recent job
Recent job: 11-year-old Mirage Duette at a roastery cafe in Pasadena, owner reported gradual shot-temperature drift over 6 months. Diagnosed thermo-syphon flow imbalance with calcium scale at the restrictor; secondary finding was a sluggish PID sensor probe (replacement age). Cleaned the loop, replaced the probe, recalibrated each group with a Scace tool. Total: 4 hours, $580 parts and labor. The machine was pulling shots within 0.4°C of target on all groups before we left.
Honest opinion
If you are buying a used Kees, the seller's water-filtration history matters more than any other variable. We have seen 15-year-old Mirages that pull better than 4-year-old ones because the older one had Everpure 7CB5 cartridges changed every 9 months and the younger one ran on tap. Ask for the filter-change records before you wire-transfer.
