Product support & troubleshooting

DHE Inc. / NOBLE · concrete batch plants, reclaimers & material handling equipment.

📋 What the App Does

The DHE Maintenance app helps plant operators and technicians log and track routine maintenance on concrete batch plants — NOBLE, BIBKO, CON-E-CO, Rexcon, and Fibo Collect systems. Everything you need is on the phone at the plant:

Step-through daily, weekly, monthly, and semi-annual maintenance checklists per plant
Parts catalog with photos, and one-tap parts quote requests
Equipment manuals viewable in the app
Daily maintenance reports emailed automatically to your manager
Attach photos to flag issues
Works offline in the field — syncs when you're back on signal

🛠️ Getting Started

1Add your plant

On the home screen tap + Add Plant, pick the plant type (NOBLE 100, BIBKO, etc.), and enter the name and serial number. The plant card appears on your home screen.

2Run a maintenance check

Tap a plant, then Maintenance Guide. Choose the interval tab — Daily, Weekly, Monthly, or Semi-Annual — and check off each task as you complete it. Only the intervals that apply to your plant type are shown.

3Send the daily report

When the day's tasks are done, tap Send Report at the bottom. The report emails to your manager automatically. The light on the plant page shows green once the daily report has been sent.

4Parts & manuals

From a plant, open Parts to browse the catalog and request a quote, or Manual to read the equipment documentation.

5Reminders

Turn on reminders per plant to get a notification when maintenance is due. Allow notifications when the app asks, so reminders can reach you.

❓ Troubleshooting & FAQ

My report didn't send / I got an email error

Check your internet connection first. If you're offline, the report is queued and sends automatically once you're back on signal. If you're online and it still fails, close and reopen the app, then resend. If it continues, contact support with the plant name and the time you tried.

I'm in the field with no signal — will I lose my work?

No. The app works offline. Your checked-off tasks, reports, and parts quotes are saved on the phone and sync automatically the next time you have a connection. You don't need to do anything.

I'm not getting maintenance reminders

Make sure notifications are allowed for the app: iPhone Settings → Notifications → DHE Maintenance → Allow Notifications. Also confirm the reminder toggle is on for that specific plant. Reminders only fire when they're enabled per plant.

A part photo or manual won't open

This usually means the file is still syncing or you're offline. Reconnect to the internet and reopen the app to pull the latest catalog and manuals. If a specific item is still missing after syncing, let support know which plant and part.

The parts list shows the wrong plant's parts

The catalog refreshes on a timer. Force it by closing and reopening the app while online, or reinstall for an immediate refresh. If it persists, contact support.

A plant I removed (or one my manager restored) isn't showing correctly

Restored plants reappear the next time you open or foreground the app while on the home screen. Fully close the app and reopen it if you don't see the change right away.

How do I request a parts quote or a new plant estimate?

For parts: open a plant → Parts → select the part → request a quote. For a new plant: on the home screen tap Request a Plant Estimate. Both send straight to our team, and we'll reply to the email you provide.

How do I update the app?

Updates come through the App Store. Open the App Store, search "DHE Maintenance," and tap Update if one is available. Keeping the app current ensures you have the latest checklists and fixes.

🔒 Privacy & Data

The DHE Maintenance app is a work tool for logging equipment maintenance. It is designed to collect only what's needed to do that job.

What the app stores

Plant & maintenance records — plant names, serial numbers, checklists, completion status, and notes you enter.
Contact details you provide — manager email for reports, and customer/contact info you enter for parts quotes or estimates.
Photos — only images you choose to attach to a task or issue.

Most data lives on your device and is synced to DHE's secure server so maintenance reports and records are available to your team.

How it's used

To email daily maintenance reports to the manager address you set.
To route parts-quote and estimate requests to the DHE team so we can respond.
To keep your plant records, manuals, and parts catalog available across sessions.

What we don't do

No advertising, and no selling or sharing of your data with advertisers.
No location tracking and no analytics profiling of individuals.
Data is used only to operate the maintenance app and support your equipment.

Data requests

To ask about, correct, or delete data associated with your account or plants, contact us at thumphrey@dhenoble.com or call (209) 835-2222.
