TLDR
On your eikon® e2s unit, error E087 indicates a constant key press on the Quick Touch Screen (QTS), causing the oven to cease operation. This typically results from debris under the screen overlay or a faulty QTS assembly. Begin by checking for obstructions and ensuring firmware is updated before considering hardware replacement.
Technical Details
Repair Steps:
- Firmware Update: Ensure the unit’s firmware is running the latest version. Outdated firmware can sometimes cause display anomalies or misinterpretations of touch input. Refer to www.merrycheftechnical.com for the most recent updates and instructions.
- Inspect for Debris: Power off the unit and carefully examine the area between the QTS screen and its protective overlay film. Even small particles can create constant pressure, mimicking a continuous touch input. Gently clean this area if any debris is found.
- Verify QTS Assembly Installation: Confirm that the QTS assembly is correctly seated and securely installed. A loose or improperly fitted assembly can lead to erratic touch responses or false readings.
- Replace Overlay & Calibrate: If debris isn’t the issue, the touchscreen overlay itself might be damaged or worn. Replace the overlay, thoroughly clean the underlying glass of the touchscreen, and then execute a full screen calibration as per the manufacturer’s instructions.
- Replace QTS Assembly: As a final step, if the error persists after all previous troubleshooting, the entire QTS assembly may be defective and require replacement. This ensures the touch panel is functioning correctly.

A: Often, yes. Checking for debris under the screen overlay, ensuring proper QTS assembly installation, and updating firmware are common initial fixes that don’t require new parts.
Q: How do I perform a screen calibration on my eikon® e2s?
A: The specific steps for screen calibration are usually found in the oven’s service manual or by contacting Merrychef technical support. It typically involves accessing a service menu and following on-screen prompts to touch specific points.
